Abstract
Purpose
The present work aims to investigate the capabilities of accurately predicting the six-degrees-of-freedom (6DoF) trajectory and the flight behavior of a flare-stabilized projectile using computational fluid dynamics (CFD) and rigid body dynamics (RBD) methods.
Design/methodology/approach
Two different approaches are compared for calculating the trajectory. First, the complete matrix of static and dynamic aerodynamic coefficients for the projectile is determined using static and dynamic CFD methods. This discrete database and the data extracted from free-flight experiments are used to simulate flight trajectories with an in-house developed 6DoF solver. Second, the trajectories are simulated solving the 6DoF motion equations directly coupled with time resolved CFD methods.
Findings
Virtual fly-out simulations using RBD/CFD coupled simulation methods well reproduce the motion behavior shown by the experimental free-flight data. However, using the discrete database of aerodynamic coefficients derived from CFD simulations shows a slightly different flight behavior.
Originality/value
A discrepancy between CFD 6DoF/RBD simulations and results obtained by the MATLAB 6DoF-solver based on discrete CFD data matrices is shown. It is assumed that not all dynamic effects on the aerodynamics of the projectile are captured by the determination of the force and moment coefficients with CFD simulations based on the classical aerodynamic coefficient decomposition.

Abstract
This chapter presents two examples of misinterpretation of the philosophical term and historical concept of human dignity in contemporary legal theory and practice. Current legal theories (R. Alexy) still introduce Pico’s concept of dignity regarding the human personality and personal (volitional and rational) abilities. The term ‘dignity’ is marginal for Pico and shows the spiritual way to the status of the original Adam. Pico’s concept of dignity is located in the area of spirit (hyperphysics), not metaphysics (soul) or physics (materials). Günter Dürig in his commentary to Grundgesetz also used the Kantian concept of human dignity. Dürig exaggerated this value and used it also for the area of physics (to protect the human being as a personality). For Kant, the term ‘dignity’ was also marginal, and he used it in the area of metaphysics (soul – especially the moral and rational parts), regarding transcendence for homo noumenon, not for homo phaenomenon. In general, it seems to be problematic to use the ideal of the dignity for the law, which regulates the social relations between concrete phenomenal personalities. There are parallels to Pico. The Kantian starting point was different from Pico, because Kant stays in the area of metaphysics (especially the moral and rational parts). Both consider freedom as a condition of dignity. The concept of autonomy of will is significant for both, but each thinks of it in different ways. For both, human being can become master of oneself, but in a different context.

Abstract
Nobody concerned with political economy can neglect the history of economic doctrines. Structural changes in the economy and society influence economic thinking and, conversely, innovative thought structures and attitudes have almost always forced economic institutions and modes of behaviour to adjust. We learn from the history of economic doctrines how a particular theory emerged and whether, and in which environment, it could take root. We can see how a school evolves out of a common methodological perception and similar techniques of analysis, and how it has to establish itself. The interaction between unresolved problems on the one hand, and the search for better solutions or explanations on the other, leads to a change in paradigma and to the formation of new lines of reasoning. As long as the real world is subject to progress and change scientific search for explanation must out of necessity continue.

Abstract
Purpose
There is a growing demand for healthy food across multicultural societies, and there are few exploratory studies that examined the motivations behind healthy eating. The purpose of this study is to explore the motives and understand the perceptions of healthy eating and how the online community conceptualizes their healthy eating.
Design/methodology/approach
Data were collected from the online community, such as posts and comments on YouTube channels, Facebook, Twitter and blogs using the hashtags (#healthyeating, #healthylifestyle, #foodforyourhealth, #culinarymedicine, #functionalfood and #nutrition). Content related to healthy eating was transcribed manually. Consumer motives regarding healthy food choices were explored using qualitative data analysis software using thematic analysis and applying Kozinet’s steps for data analysis. By examining communication on YouTube, Twitter, Facebook and blogs, this online study will help us to understand the motives behind healthy food choices.
Findings
Respondents appeared to rate food goods’ healthiness on a spectrum. Healthy eating can be conceptualized at both the concrete and abstract representation levels. The themes that emerged through thematic analysis were healthy lifestyles, culinary medicine and the perceived benefits of food.
Practical implications
This study will guide policymakers and marketers of food products on how to develop strategies while making food products for multicultural societies. Social networking platforms are used to disseminate information on healthy eating to the online community.
Originality/value
The results that were found express the need for healthy food as well as health-related problems and diseases, and they reflect subjects of interest. Social networking sites give healthcare professionals a forum to interact with and educate the online community about nutrition and health. A health care provider can actively participate in online discussion to establish rapport, respond to questions and serve as a reliable source of factual information.

Abstract
Purpose
To review and provide a new perspective on how Wroe Alderson contributed to marketing theory, and rekindle interest in his lines of research and the further development of marketing theory.
Design/methodology/approach
A metaphor is woven into the paper to provide a new way of thinking about Alderson and his work. This provides an alternative to the more traditional analyses and comparison of Alderson's work that suggests new linkages and ways of looking at his theories, constructs and concepts.
Findings
Alderson was a creative, hard working, practical marketing theorist with a drive to develop a theory of marketing. He challenged underlying assumptions of marketing, and set the discipline on a new course. Alderson himself worked on a general theory of marketing, and also inspired others to work on marketing theories. His approach and ideas still have value to today's marketing scholars.
Practical implications
Marketing scholars will benefit by taking up Alderson's work where he left off, as well as integrating the research completed since his death with his theory of marketing.
Originality/value
This paper uses a unique method to look at one of the key influencers of marketing; a metaphor encourages one to look at how Alderson was able to significantly impact the field of marketing, and suggests that there is still value in his work to today's marketing scholars. It also evokes ways that marketing theory can be further developed.

Abstract
Purpose
Sport is an important economic activity, and understanding the role of teams and managers is necessary, yet managers – specifically their brand personas – have been the subject of limited research. The purpose of this research is to explore the brand persona of a football manager, using Arsène Wenger as a case.
Design/methodology/approach
Due to the exploratory nature of the study, qualitative methods were used to explore the brand-building activity. Media reports and images that centred on Arsène Wenger's words covering a three-year period were analysed. In total, 1364 articles and 23 images were analysed in NVivo, using both a priori and emergent codes.
Findings
The findings show the construction of the brand persona in three main dimensions pertinent to his role as a manager. The first is the performance in the managerial role in which Arsène Wenger is appointed, the second is associated with the person (including emotions and self-expression) and the third is the context (i.e. football) in which the manager operates.
Research limitations/implications
The research focused on one manager while he was managing a premier league club and is limited to England.
Practical implications
While proposing a theoretical model, this study proposes football clubs understand a manager's persona in relation to the club's brand and the interactive effect. The support of the club on the persona is also indicated.
Originality/value
Football managers have received some research attention, but there has been no analysis of their brand personas. This study expands the understanding of the contribution of the manager to the club brand.

Abstract
Purpose
The purpose of this paper is to investigate the underlying knowledge structure and evolution of industrial-buying research published between 1965 and 2015.
Design/methodology/approach
Bibliometric analysis is performed on 357 relevant papers (using principal component analysis and natural language processing, using VantagePoint® tools, used to generate bubble maps, auto-correlation maps and Aduna cluster maps), demonstrating how various factors involved in industrial buying have evolved, their degree of correlation with each other and the interrelationships of multiple factors concerning their co-occurrences.
Findings
The systematic mapping of industrial-buying research would illustrate the development of the significant factors in industrial-buying research. This paper provides both a global perspective on the leading countries and journals in the field and a robust roadmap for further investigation in this field.
Research limitations/implications
This paper is limited to the data considered for analysis and may, therefore, overlook or underestimate some work that has not been captured while filtering databases related to industrial buying.
Practical implications
This paper facilitates near-future projection and trend analysis in industrial-buying research.
Originality/value
The methodology used is unique to the field of business-to-business marketing.

Abstract
Purpose
Turnover in high-tech companies has long been a concern for managers and executives. Recent meta-analyses from the general turnover literature consistently show that job satisfaction is a major attitudinal antecedent to turnover intention and turnover behavior. Additionally, the available research on information technology (IT) employees focuses primarily on turnover intentions and not on a risky decision-making perspective and actual turnover (turnover behavior). The paper aim is to focus on that.
Design/methodology/approach
This study uses hierarchical ordinary least squares, process (Preacher and Hayes, 2004) and logistic regression.
Findings
The main predictor of actual turnover is risky decision-making, whereas job satisfaction is the main predictor of turnover intention.
Originality/value
The joint effects of risk and job satisfaction on turnover intention and behavior have not been studied in the IT domain. Hence, this study extends our understanding of turnover in general and particularly among IT employees by studying the combined effect of risk and job satisfaction on turnover intentions and turnover behavior. The study’s theoretical and practical implications are likewise discussed.
