Abstract
Purpose
This paper aims to present the results that can be achieved using continuous three-dimensional (3D) printing technology.
Design/methodology/approach
In the first section, conventional additive manufacturing and continuous 3D-printing are described and compared against each other. Essential is the new approach to coat the particulate material and to print it on a tilted surface. For this special setup, theoretical considerations for sources of distortions are given. These considerations define the design of the test parts. For the evaluation of a tilted setup a prototype using large dimensions is shown. Of special interest is the exact transportation using a large mass of particulate material.
Findings
The 3D-printing principle is suitable for tilted surfaces, making production without any downtime possible. The parts produced using the prototype continuous 3D-printer have sufficient accuracy for foundry use, although various considerations and the setup show that angular deflections can be caused by inaccuracies in the feeding system.
Research limitations/implications
The parts’ accuracy is additionally affected by the thickness of unbound particle material under the building area. The amount of unbound particle material is of a constructive nature. Thus, the setup is limiting the investigations. Using the current material system, the printing should take place as near to the conveyor belt as possible.
Practical implications
This paper outlines which kind of parts can be manufactured using continuous 3D-printing.
Originality/value
This article shows a first evaluation of parts printed using continuous 3D-printing. It gives a perspective on future designs from rapid prototyping machines based on these principles and shows the possible benefits. The change over from rapid prototyping to rapid manufacturing will be strongly accelerated by said machine design.

Abstract
Spirituality is a concept that explains the spiritual dimension of human beings. Meaning of life, being together, and the bigger one's existence are the components of spirituality. In that manner, workplace spirituality is an area that endeavors to find the meaning of the work together with the community. Research reveals that workplace spirituality has several dimensions, and inner life, sense of community, and meaning at work are validly used. Though developing in the research area, misunderstandings and misuses of the phenomenon causes several dark sides. In this context, this chapter aims to reveal these in five aspects to contribute to enhancing the literature. The ambiguity in defining spirituality and religion is the first dark point in understanding workplace spirituality. Accepting spiritual executions at work as a tool for profitability is the second. The scarcity of awareness of executive leaders about workplace spirituality is the other. Considering the studies on workplace spirituality as a fad and the expected difficulties in developments about the area is the fourth. Finally, workplace spirituality-based misbehaviors at work are the last dark side, addressed in this study. In addition to the explanations in its content, the authors present a bibliometric analysis conducted by R. The chapter concludes with general evaluations and suggestions for future studies.

Abstract
Tail-dependence evolution for the symmetrized Joe–Clayton copula is proposed to depend on an exponentially weighted moving average (EWMA) of the absolute difference in probability integral transforms. Using these dynamics, time-varying tail dependence between bank and insurance equity prices is assessed in a parametric copula, generalized autoregressive conditional heteroscedastic framework. The results suggest a relatively long lag and support the EWMA lag structure as an effective estimation vehicle. Tail dependence is shown often to tend higher during periods of market stress.

Abstract
The collection of chapters in this 30th volume of Advances in Econometrics provides a well-deserved tribute to Thomas B. Fomby and R. Carter Hill, who have served as editors of the Advances in Econometrics series for 25 and 21 years, respectively. Volume 30 contains a more varied collection of chapters than previous volumes, in essence mirroring the wide variety of econometric topics covered by the series over 30 years. Volume 30 starts with a chapter discussing the history of this series over the last 30 years. The next five chapters can be broadly categorized as focusing on model specification and testing. Following this section are three contributions that examine instrumental variables models in quite different settings. The next four chapters focus on applied macroeconomics topics. The final chapter offers a practical guide to conducting Monte Carlo simulations.

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
The purpose of this historical paper is to examine arguably the most controversial advertising campaign of all time. Critics have condemned tobacco marketer George Washington Hill's “Reach for a Lucky Instead of a Sweet” campaign in the late 1920s and early 1930s for its explicit attempt to encourage smoking among women by linking cigarettes with themes of slenderness and youth.
Design/methodology/approach
The paper relies on primary sources obtained chiefly from the important advertising trade journals Printers' Ink and Advertising and Selling. Many sources, in turn, pointed to historically significant advertisements from the “Reach for a Lucky […]” campaign, some of which are included among the findings. Tentative themes of analysis were: the strategic motives behind the “Reach for a Lucky […]” campaign and the campaign's outcomes and consequences, both positive and negative.
Findings
Hill aggressively pursued the female smoker of the 1920s, as did other cigarette marketers of the period. However, the paper's findings support a conclusion that Hill had additional motives for attacking “sweets,” other than merely encouraging women to smoke with a slenderness appeal. Hill's primary strategic concern must have been how to address the extraordinarily competitive situation he faced with the other “big four” cigarette brands.
Originality/value
Focusing on the strategic intent of the campaign and its outcomes and consequences, findings strongly suggest that prior perspectives and conclusions found in advertising history texts regarding this infamous campaign often fail to reveal its significance as an historical event.

Abstract
The increasing pressure for social responsibility and sustainability that multinational enterprises (MNEs) are facing in their global operations represents one important emerging phenomenon within the international business field. In this book chapter, we present an in-depth case study on how a global fashion MNE develops and implements sustainability practices in their operations in an emerging market context. The case study focusses on the MNE’s work related to energy efficiency and renewable energy in the production market of Bangladesh. The purpose of this chapter is to advance the understanding about particular practices pertinent to a proactive approach to corporate social responsibility (CSR). The chapter contributes to ongoing discussions within the international business field on the role of MNEs in driving and implementing sustainability practices. We add an in-depth understanding of the proactive CSR practices undertaken by an MNE, in an emerging market context.

Abstract
Purpose
The purpose of this paper is to review empirical studies on process mining in order to understand its use by organizations. The paper further aims to outline future research opportunities.
Design/methodology/approach
The authors propose a classification model that combines core conceptual elements of process mining with prior models from technology classification from the enterprise resource planning and business intelligence field. The model incorporates an organizational usage, a system-orientation and service nature, adding a focus on physical services. The application is based on a systematic literature review of 144 research papers.
Findings
The results show that, thus far, the literature has been chiefly concerned with realization of single business process management systems in single organizations. The authors conclude that cross-system or cross-organizational process mining is underrepresented in the ISR, as is the analysis of physical services.
Practical implications
Process mining researchers have paid little attention to utilizing complex use cases and mining mixed physical-digital services. Practitioners should work closely with academics to overcome these knowledge gaps. Only then will process mining be on the cusp of becoming a technology that allows new insights into customer processes by supplying business operations with valuable and detailed information.
Originality/value
Despite the scientific interest in process mining, particularly scant attention has been given by researchers to investigating its use in relatively complex scenarios, e.g., cross-system and cross-organizational process mining. Furthermore, coverage on the use of process mining from a service perspective is limited, which fails to reflect the marketing and business context of most contemporary organizations, wherein the importance of such scenarios is widely acknowledged. The small number of studies encountered may be due to a lack of knowledge about the potential of such scenarios as well as successful examples, a situation the authors seek to remedy with this study.
