How value and trust influence loyalty in wireless telecommunications industry
2012
Despite making significant investments in enhancing the customer service experience, long-term customer loyalty remains an elusive dream for many service providers. Particularly in the telecommunications industry, switching providers even from within continuous contract relationships is easy and companies struggle to retain their customers. Trust and value are considered cornerstones of long-term relationships, so it is perhaps surprising that previous research on how relationship age and usage level actually affect value, trust and loyalty is inconclusive. The current research is set in the telecommunications services field and draws on a large-scale survey undertaken in Finland. The findi…
What causes COVID-19 vaccine hesitancy? Ignorance and the lack of bliss in the United Kingdom
2022
AbstractUnderstanding vaccine hesitancy has become increasingly important during the COVID-19 pandemic as governments around the globe have been struggling to convince portions of their populations to participate in vaccination protocols. Here we report on a nationally representative survey of the United Kingdom in which data revealed that individuals showed more willingness to take fictitious vaccines (putatively produced by the US government Medicare program and the now defunct healthcare company Theranos) than to take the Sputnik and Sinovac vaccines (developed by the Russian and Chinese governments respectively). The data indicate that the critical factor in vaccine hesitancy among the …
Fuzzy Investment Portfolio Selection Models Based on Interval Analysis Approach
2012
Published version of an article from the journal: Mathematical Problems in Engineering. Also available from the publisher:http://dx.doi.org/10.1155/2012/628295 This paper employs fuzzy set theory to solve the unintuitive problem of the Markowitz mean-variance (MV) portfolio model and extend it to a fuzzy investment portfolio selection model. Our model establishes intervals for expected returns and risk preference, which can take into account investors' different investment appetite and thus can find the optimal resolution for each interval. In the empirical part, we test this model in Chinese stocks investment and find that this model can fulfill different kinds of investors' objectives. Fi…
Responsible I(m)ovation in Asia Pacific regions
2022
AbstractOver the past 20 years, a debate has developed on the differences between innovation and imitation strategies as mechanisms by which businesses operating in the Asia Pacific region may gain a competitive advantage. The current research contributes to this debate from a different perspective by exploring some of the challenges and opportunities associated with the combination of both strategies into what has been defined as imovation. Imovators and imovations do not stand alone in business ecosystems. Rather, they should be embraced in the context of sustainability-related virtues and emerging capabilities, such as ethical behaviour, co-responsibility and positive social impact. Taki…
The language of profit warnings: a case of denial, defiance, desperation and defeat
2021
PurposeTaking a communication perspective, the paper explores management's rhetoric in profit warnings, whose sole purpose is to disclose unexpected bad news.Design/methodology/approachAdopting a close-reading approach to text analysis, the authors analyse three profit warnings of the now-collapsed Carillion, contrasting the rhetoric with contemporaneous investor conference calls to discuss the profit warnings and board minutes recording boardroom discussions of the case company's precarious financial circumstances. The analysis applies an Aristotelian framework, focussing on logos (appealing to logic and reason), ethos (appealing to authority) and pathos (appealing to emotion) to examine h…
Time series momentum in the US stock market: Empirical evidence and theoretical analysis
2022
There is much controversy in the academic literature on the presence of short-term trends in financial markets and the trend-following strategy’s profitability. We restrict our attention to studying the time series momentum in the S&P Composite stock price index. Our contributions are both empirical and theoretical. On the empirical side, we present compelling evidence of the presence of short-term momentum. For the first time, we suppose that the returns follow a -order autoregressive process and evaluate this process’s parameters. On the theoretical side, we develop a tractable theoretical model that contributes to our fundamental understanding of the trend-following strategy’s risk, retu…
Creating value through autonomous shipping: an ecosystem perspective
2022
AbstractThe expected benefits of Maritime Autonomous Surface Ships (MASS) include increased safety, reduced costs and increased earning potential due to operational efficiencies and reduction in vessel manning. However, autonomous shipping enabled by such ships bears a greater potential than just replacing humans with machines. Rather, MASS can play a role in transforming supply and logistics chains. The value creation potential of these ships depends on the degree to which they disrupt logistics. Our aim here is to clarify how MASS create value and for whom, as well as how different actors in the maritime logistics ecosystem are able to monetize or otherwise benefit from the innovation. Ba…
Unethical Leadership: Review, Synthesis and Directions for Future Research
2022
AbstractThe academic literature on unethical leadership is witnessing an upward trend, perhaps given the magnitude of unethical conduct in organisations, which is manifested in increasing corporate fraud and scandals in the contemporary business landscape. Despite a recent increase, scholarly interest in this area has, by and large, remained scant due to the proliferation of concepts that are often and mistakenly considered interchangeable. Nevertheless, scholarly investigation in this field of inquiry has picked up the pace, which warrants a critical appraisal of the extant research on unethical leadership. To this end, the current study systematically reviews the existing body of work on …

Impact of ethical certifications and product involvement on consumers decision to purchase ethical products at price premiums in an emerging market c…
2021
AbstractIn emerging markets, instances of increasing consumers focus on ethical aspects of the product are observed. To this end, we aim to examine the influence of two ethical certifications and two product involvement types on consumers willingness to purchase ethical products at price premiums in the Indian market. No animal cruelty certification and no child labor certification are chosen as the ethical certifications, and a shirt and a bar of soap are chosen as high and low involvement product categories. Data is collected from 206 respondents for the experiment, in which consumers willingness to purchase a product is evaluated for different product scenarios. The results of the study …
