Presently in multicolor fused filament-based three-dimensional (3-D) printing, significant amounts of waste material are produced through nozzle priming and purging each time a change from one color to another occurs. G-code generating slicing software typically changes the material on each layer resulting in wipe towers with greater mass than the target object. The purpose of this study is to provide an alternative fabrication approach based on interlayer tool clustering (ITC) for the first time, which reduces the number of tool changes and is compatible with any commercial 3-D printer without the need for hardware modifications.

The authors have developed an open-source PrusaSlicer upgrade, compatible with Slic3r-based software, which uses the described algorithm to generate g-code toolpath and print experimental objects. The theoretical time, material and energy savings are calculated and validated to evaluate the proposed fabrication method qualitatively and quantitatively.

The experimental results show the novel ITC method can significantly increase the efficiency of multimaterial printing, with an average 1.7-fold reduction in material use, and an average 1.4-fold reduction in both time and 3-D printing energy use. In addition, this approach reduces the likelihood of technical failures in the manufacturing of the entire part by reducing the number of tool changes, or material transitions, on average by 2.4 times.

The obtained results support distributed recycling and additive manufacturing, which has both environmental and economic benefits and increasing the number of colors in a 3-D print increases manufacturing savings.

Infrastructure projects are pivotal for regional economic development, but also face low project effectiveness. Leadership is always regarded as a key enabler for project team effectiveness, including vertical leadership and team-level leadership. The purpose of this paper is to examine how vertical leadership facilitates shared leadership in infrastructure project teams.

This paper develops the conceptual model based on the literature review. Then the questionnaire survey was conducted. The empirical data obtained from 117 infrastructure project teams in China were analyzed by partial least squares structural equation modeling (PLS-SEM) for validating the proposed model. Finally, the results were comparatively discussed to explain the dual-pathway between vertical leadership and shared leadership. And the practical implications were presented for the project managers in infrastructure project teams.

Drawing on social learning theory and social cognitive theory, the results show that both participative leadership and task-oriented leadership can facilitate shared leadership. Further, team atmosphere fully mediates the link between participative leadership and shared leadership. Team efficacy fully mediates the relation between task-oriented leadership and shared leadership. Also, role clarity has a negative moderating effect on the former path.

The study extends the knowledge of leadership theory in the construction field. Based on the proposed conceptual model and PLS-SEM results, this study unveils the black box between vertical leadership and shared leadership and contributes to the theory of leadership on how the impact of different vertical leadership on team process promotes shared leadership.

The therapeutic community (TC) is an environmental intervention where principles of working together democratically can enhance self-agency. While availability of inpatient TCs within the UK National Health Service (NHS) has declined, shorter or alternative interventions using core TC approaches have shown promise in enacting change. The purpose of this paper is to report and reflect on the development and running of a pilot nano-TC.

Foundations Group was a 2-h TC group intervention set up and run within the NHS for 18 months in 2021–2022, and taking place on City Farm premises. The group was convened as part of the complex emotional needs service in a mental health NHS Trust in the South West of England. Over the study period, the group comprised 11 members, one peer member and three staff members.

The authors reflected on the TC stance of working democratically with a fluid hierarchy, taking a non-expert approach, and using support and challenge to enhance self-agency and belongingness. The authors have detailed the structure of the group session including use of community meetings, psychoeducation, creative sessions and reviews. Members took on roles within the group including chairing sessions.

This group was a novel service within the NHS Trust where it was conducted and may represent a standalone therapeutic group. The authors hope it will show that core TC principles can be applied in shorter interventions than have previously been used.

Effective experience design requires not only a knowledge of tourist goals, but an understanding of how these can be met in a particular tourism site. Research on experiences and experience design is supported by cognitive psychology concepts such as perception, attention, appraisal, emotion, consciousness, feelings and memory. However, these concepts are often used in a combination with others from sociology, social or environmental psychology in a manner that leads to confusion rather than clarity, without apparent understanding of the theoretical mechanisms by which these concepts are related. This chapter develops a series of propositions for potential application to tourism experience design. Future research should examine the efficacy of these propositions from cognitive psychology for tourism experience design.

Marketing tourism is essential for long-term tourism development which requires gaining knowledge about the motivation and needs of tourists. In order to help tourists gain a hospitable experience, information regarding the needs, perception, and their behavior while on site is important. This research attempts to explore the priority of tourists’ needs in visiting historical sites. It also tries to conceptualize new forms of hospitality strategies for smart tourism development. Based on grounded theory, Maslow’s hierarchy of needs is conceptualized for historical tourists and used as the main framework for this work. The Persepolis-Pasargadae Historical Range (PPHR) is chosen as the case study of the research because of the historical and cultural attractions located in this historical range. Results indicate that tourists interested in visiting this destination are looking to fulfill their growth needs. These growth needs can be complemented by new technologies while on site such as virtual reality (VR) goggles that help tourists gain knowledge about the reality of these destinations. The research concludes with findings and suggestions that can contribute to the planning of an effective marketing plan based on tourists’ motivation and needs for visiting historical destinations.

Mindfulness, a kind of mental perception, has a long history in Buddhist spiritual traditions, but has also a well-developed use in clinical psychology as a mental health intervention. Meditative mindfulness provides therapeutic benefits in the treatment of mental trauma. Recently, an interest in the outcomes derived from meditative mindful experience has emerged in tourism studies. Tourists experiencing a mindful-like event may get a sense of peacefulness and a harmonic relationship between the self and the environment. This chapter discusses how meditative mindfulness can be integrated into tourism experiences and create subtle therapeutic-like effects. Theoretically, this study bridges the relationship between a meditative mindful tourist experience and its perceived consequences. Practically, it explains how to generate mental health outcomes from tourism experiences.

War is one of the worst characteristics of human nature. Wars over territory, religion, and governance were and are always present through history. War and tourism seem dissonant at first glance. However, the post effects of war enable its components, such as battlefields and artefacts, to become tourist attractions. People share the impetus to visit war attractions such as battlefields, military museums, cemeteries, memorials, and other war-related sites. There is a supply for this type of tourism in exchange for the demand. This type of tourism is referred to in the literature as battlefield tourism. The meaning and definition of battlefield tourism are the main aim of this chapter. What is battlefield tourism? What are the components of battlefield tourism? How can battlefield tourism be defined? These are the primary questions this study tries to address.

This chapter offers an insightful exploration into the burgeoning field of eco-tourism, focusing on the expectations and motivations of tourists gravitating towards green destinations. Eco-tourism, while not a novel concept, has seen a significant resurgence in interest over the past few decades, with its roots tracing back to the wildlife reserves of Kenya in the 1960s. The narrative then transitions to an in-depth examination of what constitutes a green destination, emphasizing its foundational pillars, such as environmental conservation, sustainable tourism practices, active community engagement, educational initiatives, and the pursuit of certifications that affirm their commitment to sustainability. A central theme of the chapter is the nuanced expectations of eco-tourists who are increasingly seeking destinations that not only offer the tranquillity and beauty of nature but also adhere to sustainability principles and cultural authenticity. These expectations are intricately linked to the motivations driving tourists towards green destinations, including the desire to connect with nature, contribute to conservation efforts, and engage in travel practices that are both responsible and enriching. By weaving together theoretical insights and empirical evidence, the chapter provides a comprehensive understanding of the dynamic interplay between the demand for green destinations and the supply of sustainable tourism experiences, ultimately highlighting the critical role of eco-tourism in paving the way for a more sustainable and ethical travel industry.
