    • Understanding and predicting bank rating transitions using optimal survival analysis models

      Louis, Philippe; Van Laere, Elisabeth; Baesens, Bart (Economics Letters, 2013)
      In the aftermath of the financial crisis, this study investigates which underlying determinants cause bank rating transitions. We develop survival analysis models to explain credit transition hazards using macroeconomic factors and the rating history. We find that there exists a significant dependence of rating upgrade or rating downgrade transition hazards on rating-specific covariates and macro-economic covariates. Our results confirm the momentum effect, meaning that a financial institution that has been recently upgraded/downgraded has a higher chance of being upgraded/downgraded again. The predictive performance of the developed models turns out to be satisfactory.
    • Understanding envy through narrative fiction

      Patient, David; Lawrence, Thomas; Maitlis, Sally (Organization Studies, 2003)
      In this article, we explore the social construction of workplace envy through an analysis of its portrayal in a fictional narrative. Based on our examination of three excerpts from Richard Russo's novel Straight Man, we argue that envy is socially constructed in prominent and revealing episodes within broader organizational narratives. We further show that envy both serves as a catalytic emotion that engenders action and sensemaking, and at the same time, acts as a mechanism that reproduces the moral and cultural order within which it occurs.

    • Understanding the continuation of firm activities when entrepreneurs exit their firms: Using theory of planned behavior

      Leroy, Hannes; Manigart, Sophie; Meuleman, Miguel; Collewaert, Veroniek (Journal of Small Business Management, 2015)
      Up to now, little attention has been paid to the continuity of a firm when entrepreneurs exit. Survey data from 175 entrepreneurs confirm the theory of planned behavior as an appropriate framework to understand whether entrepreneurs, when leaving, sell or liquidate their firm. Entrepreneurs' sale attitudes are related to sale intentions, which are associated with firm sale. Further, sale attitudes are positively related to whether entrepreneurs perceive firm continuation to be out of free will, their experience, the number of employees, and whether the firm is a multigeneration family business.

    • Understanding today's music acquisition mix: a latent class analysis of consumers' combined use of music platforms

      Weijters, Bert; Goedertier, Frank (Marketing Letters, 2016)
      In response to diversifying music delivery modes, consumers increasingly combine various music platforms, both online and offline, legal and illegal, and free or paying. Based on survey data (N?=?685), the current study segments consumers in terms of the combination of music delivery modes they use. We identify four latent classes based on their usage frequency of purchasing CDs, copying CDs, streaming music, streaming music videos, peer-to-peer file sharing, and purchased downloading. All-round users (9.9 %) use most or all acquisition modes, but at a low frequency. Traditionalist (33.7 %) typically makes no use of any of the acquisition modes except buying CDs. Streamers-downloaders (20.7 %) use several acquisition modes intensively, especially streaming (video and/or music only) and downloading (legal and illegal). Light users (35.6 %) also use multiple acquisition modes, but less frequently. We draw theoretical and practical implications, discuss limitations, and suggest ideas for future research.
    • Unfolding the concept of a TMT-Diversification strategy fit

      Weiss, Martin; Schneider, D.; Lebid, J. (Team Performance Management: An International Journal, 2015)
      This paper aims to develop a conceptual foundation of a fit between top management teams (TMTs) and their company's corporate strategy. The authors fortify the importance of the concept of fit if the impact of upper echelons on organizational performance is trying to be explained. Yet, a constitutive concept of fit for the corporate strategy, a particularly important dimension of strategy, was previously neglected.
    • The unhealthy = tasty belief is associated with BMI through reduced consumption of vegetables: A cross-national and mediational analysis

      Briers, Barbara; Huh, Young Eun; Chan, Elaine; Mukhopadhyay, Anirban (Appetite, 2020)
      Obesity is one of the greatest public health challenges of modern times and its prevalence is increasing worldwide. With food so abundant in developed countries, many people face a conflict between desires for short-term taste and the goal of long-term health, multiple times a day. Recent research suggests that consumers often resolve these conflicts based on their lay beliefs about the healthiness and tastiness of food. Consequently, such lay beliefs can play critical roles not just in food choice but also weight gain. In this research, we show, across six countries and through mediation analysis, that adults who believe that tasty food is unhealthy (the Unhealthy = Tasty Intuition, or “UTI”; Raghunathan, Naylor, & Hoyer 2006) are less likely to consume healthy food, and thereby have a higher body mass index (BMI). In Study 1, we conducted a cross-sectional survey in five countries (Australia, Germany, Hong Kong, India, and the UK), and found that greater strength of belief in UTI was associated with higher BMI, and this relationship was mediated by lower consumption of fruits and vegetables. The observed patterns largely converged across the sampled Western and Asian-Pacific countries. In Study 2, we teased apart the mediating role of vegetable versus fruit consumption and also addressed the issue of reversed causality by predicting BMI with a measure of UTI belief taken 30 months previously. We found that vegetable consumption, but not fruit consumption, mediated the association between UTI belief and BMI. Our findings contribute to the literature by showing how lay beliefs about food can have pervasive and long-lasting effects on dietary practices and health worldwide. Implications for public policy and health practitioners are discussed.

    • Unlocking the value of personalised healthcare in Europe — breast cancer stratification

      Van Dyck, Walter; Gassull, Daniel; Vértes, Gergely; Jain, Prateek; Palaniappan, Muhilan; Schulthess, Duane; Tambuyzer, Erik; Hudson, Richard; Moran, Nuala (Health Policy and Technology, 2012)
      Through stratification, this simulation shows that there is great potential to improve the efficiency of treating breast cancer. By segmenting the female population at the age of 50 based on family history and genetic testing, our model shows a reduction in costs of breast cancer treatments by 37% with no loss of efficacy accomplished primarily through a 60% drop in incidence of metastatic stages of the disease. These programmes are not inexpensive, and require substantial upfront investments of roughly 2 billion GBP and continued annual investments of several hundred million GBP. However, our simulations show a positive NPV and ROI in approximately year 7 of the programme.
    • Unveiling smart city implementation challenges: The case of Ghent Authors

      Van den Bergh, Joachim; Viaene, Stijn (Information Polity: The International Journal of Government & Democracy in the Information Age, 2016)
      The `smart city' label is internationally used by cities, researchers and technology providers with different meanings. As a popular concept it is widely used by city administrators and politicians to promote their efforts to prepare their cities for the future. There are decent definitions for what a smart city is, but it is much harder to find a trustworthy description of what it takes to become a smart city and how a city administration is impacted by that effort. This paper sets out to investigate how a city, aspiring to become a `smart city', can manage its internal organization to realize that ambition. Specifically, it describes the case of the City of Ghent, Belgium, and the key challenges it has been facing in its ongoing efforts to be a smart city. Based on in depth interviews with city representatives six key challenges for smart city realization were identified and tested with a panel of representatives from five European cities that are in the process of becoming a smart city. The study contributes to a more professional pursuit of the smart city concept and elaborates the academic body of knowledge on smart city development, as an instance of IT-enabled transformation in public services.

    • Use of proximal policy optimization for the joint replenishment problem

      Vanvuchelen, Nathalie; Gijsbrechts, Joren; Boute, Robert (Computers in Industry, 2020)
      Deep reinforcement learning has been coined as a promising research avenue to solve sequential decision making problems, especially if few is known about the optimal policy structure. We apply the proximal policy optimization algorithm to the intractable joint replenishment problem. We demonstrate how the algorithm approaches the optimal policy structure and outperforms two other heuristics. Its deployment in supply chain control towers can orchestrate and facilitate collaborative shipping in the Physical Internet.
