Abstract
Purpose
This paper aims to present the mathematical foundation of so-called advance algorithms, developed to compensate for defects during acceleration and deacceleration of the print head in filament-based melt extrusion additive processes. It then investigates the validity of the mathematical foundation, its performance on a low-cost system and the effect of changing layer height on the algorithm’s associated process parameter.
Design/methodology/approach
This study starts with a compilation and review of literature associated with advance algorithms, then elaborates on its mathematical foundation and methods of implementation. Then an experiment displaying the performance of the algorithm implemented in Marlin machine firmware, Linear Advance 1.0, is performed using three different layer heights. The results are then compared with simulations of the system using Simulink.
Findings
Findings suggests that advance algorithms following the presented approach is capable of eliminating defects because of acceleration and deacceleration of the print head. The results indicate a layer height dependency on the associated process parameter, requiring higher compensation values for lower layer heights. It also shows higher compensation values for acceleration than deacceleration. Results from the simulated mathematical model correspond well with the experimental results but predict some rapid variations in flow rate that is not reflected in the experimental results.
Research limitations/implications
As there are large variations in printer design and materials, deviation between different setups must be expected.
Originality/value
To the best of authors’ knowledge, this study is the first to describe and investigate advance algorithms in academic literature.

Abstract
Against the grain of the paradigmatic postcolonial analytics of the colonial state, this chapter presents a non-dichotomous comparison of two regimes within the late 18th century Danish empire, which are commonly presumed to be of essentially different kinds – namely the colonial state in Tranquebar in South East India and the metropolitan government of rural Danish society. By focusing, firstly, on practices of policing and, secondly, on the general technology of power that targeted these significantly different socio-political spheres, it is argued that these regimes were governing according to similar strategies: seeking, on one hand, to deploy societal mechanisms of self-regulation and, on the other, to provide a balance and order to the otherwise chaotic forces of the population. On the basis of a Foucauldian vocabulary of government, it is thereby argued that colonialism, at this time and place, had not yet clearly constituted itself as a particular form of rule.

Abstract
This chapter studies the tourism cluster of Majorca and its connection with collective entrepreneurship. To this end, the authors review the history of four world leading Spanish hotel companies, from their beginnings, in Majorca, in the 1950s, to their internationalization, in the 1980s and 1990s: Barceló, Meliá, Riu, and Iberostar. This allows us to identify common patterns of behaviour among them over time, which in turn illustrate the dynamics of the tourism cluster and the role played by its context. This qualitative and historical research allows us to make the following contributions: first, in line with other studies in the economic history of Spanish tourism, the four cases support the identification of Majorca as a tourism cluster. Second, the authors highlight several important characteristics of the island which reinforced and strengthened the cluster and boosted collective entrepreneurship, through an intense flow of information between the companies. Third, the authors illustrate coopetition as the key nature of the relationship between the clustered companies in a simultaneous process of competition and cooperation. Finally, the authors show how the strength of the tourism cluster, in Majorca, drove the companies to replicate the same dynamics and structures abroad.

Abstract
Purpose
The purpose of this paper is to analyse the effects of brand trust and online brand community (OBC) trust on consumer repurchase intention and the positive electronic word-of-mouth (eWOM) intention of OBC members.
Design/methodology/approach
The research model was assessed using data from a sample of 628 OBC users using partial least squares structural equation modelling (PLS-SEM).
Findings
The results show that brand trust positively affects repurchase intention and positive eWOM intention, both directly and indirectly through OBC trust. The total effect of brand trust on the results is greater than that of OBC trust.
Originality/value
This research contributes to marketing theory and practice by analysing the combined effect of OBC trust and brand trust on the consumer–brand relationship in the context of OBCs.
Propósito
El objetivo de esta investigación es analizar los efectos de la confianza en la marca y la confianza en la comunidad online de marca en la intención de los miembros de la comunidad de recomprar dicha marca y de hablar bien electrónicamente (eWOM) sobre la misma.
Diseño/metodología/enfoque
El modelo de investigación fue evaluado usando datos de una muestra de 628 usuarios de comunidades online de marca, mediante un modelo de ecuaciones estructurales por el método de mínimos cuadrados parciales (PLS-SEM).
Hallazgos
Los resultados muestran que la confianza en la marca afecta positivamente a la intención de recompra y al eWOM positivo, directa e indirectamente a través de la confianza en la comunidad. El efecto total de la confianza en la marca es mayor que el de la confianza en la comunidad.
Originalidad/valor
Esta investigación contribuye a la teoría y práctica del marketing al analizar el efecto combinado de la confianza en la marca y en la comunidad online de marca, en las relaciones consumidor-marca.

Abstract
This conceptual article presents a theoretical approach to understanding the atmosphere at sports stadiums. Using the environmental psychology behavioural model proposed by Mehrabian & Russell (1974), and taking into account recent findings in consumer research, we develop a comprehensive framework for investigating this atmosphere. The framework highlights the role of emotions elicited by different stimuli in sports stadiums. We also suggest a number of direct and indirect influences on behavioural outcomes, caused by the emotional reactions and personal predispositions of spectators - influences that are of economic relevance. The proposed framework also forms a starting point for future empirical studies.

Abstract
Travels and vacations organised by a large number of people to certain destinations in certain periods cause some negative impacts on the destinations in question. The concept of overtourism, which has become a current issue especially with the anti-tourism demonstrations in certain destinations such as Venice, Barcelona and Dubrovnik as a result of the increasing tourism carrying capacity, has been drawing attention in recent years regarding the sustainability in the destinations. Popular destinations that are affected by overtourism try to develop some strategies in order to minimise the negative impacts of overtourism. One of these strategies is the demarketing strategy that is developed by the destination stakeholders towards the target group. In this chapter of the book, the significance of the concept of demarketing in terms of struggle against overtourism was revealed and how demarketing strategies applied to the marketing mix and different strategies were approached in tourism studies was discussed in detail by addressing the current literature. In addition, suggestions were proposed to the popular destinations that feel the negative impacts of overtourism and will be affected by overtourism also in the future concerning creating their own demarketing strategies and destination planning.

Abstract
Purpose
Disruptive technologies in the global logistics industry are often regarded as a threat to the existing business models of incumbents’ companies. Existing research, however, focuses mainly on whether technologies have disruptive potential, thereby neglecting when such disruptive transitions occur. To understand the timing of potential disruptive technological change, this paper aims to investigate the elements of the underlying ecosystem shaping these transitions.
Design/methodology/approach
Building on the established ecosystem framework from Adner and Kapoor (2016a), this paper constructs four categories of technology substitution to assess how quickly disruptive change may occur in the global logistics industry and defines key technology substitution determinants in logistics to emphasize the role of ecosystems for further consideration into disruptive innovation theory.
Findings
Based on the key determinants, this paper proposes first definitions of distinctive ecosystems elements linked to the three types of innovations, namely, sustaining innovations, low-end disruptions and new-market disruptions, thereby integrating ecosystems into Christensen’s (1997) disruptive innovation theory.
Originality/value
By developing a framework that conceptualizes the pace of technology substitution, this paper contributes to a more nuanced understanding of how logistics managers and academics can better predict disruptive transitions and develop strategies to allocate resources.
