This paper aims to investigate different ways in which faculty members of sustainability-related departments in universities across the world perceive, understand and define sustainability and how these definitions are linked to their demographics and epistemological beliefs.

Scholars from different disciplines investigate the sustainability of social-ecological systems from different perspectives. Such differences in the understanding of, and approaches to, sustainability have created ambiguity within the field and may weaken its effectiveness, impact and reputation as a field of research. To contribute to the discussion about sustainability definition, a survey was conducted involving university faculty members working in sustainability-related academic departments around the world. Participants’ responses were analyzed using SPSS 24.0 involving descriptive and inferential statistics and principle component analysis. Additionally, responses to open-ended questions were qualitatively analyzed.

Factor analysis on sustainability definition items reveal four emergent universal definitions of sustainability, labeled as Environmentalism concerns, Common understanding, neo-Malthusian environmentalism and Sustainability as well-being. Statistical analyses indicate that individuals from developed countries are more likely to define sustainability as Environmentalism and Common understanding; however, individuals from developing countries tend to define sustainability as well-being. Also, more heavily engaged scholars in interdisciplinary research of sustainability are more likely to perceive sustainability as Common understanding. Logistic Regression models demonstrate a connection between epistemological perspectives of researchers and sustainability definitions. Qualitative content analysis indicates that interdisciplinarity and collaboration are the most common challenges to sustainability research.

The findings of this study demonstrate disconnects between scholars from developing and developed countries in understanding and defining sustainability, and these disconnects may present further challenges for global sustainability scholarship.

This paper aims to present a multi-axis additive robot manufacturing system (ARMS) and demonstrate its beneficial capabilities.

ARMS was constructed around two robot arms and a fused filament fabrication (FFF) extruder. Quantitative experiments are conducted to investigate the effect of printing at different orientations with respect to gravity, the effect of dynamically changing build orientation with respect to the build tray when printing overhanging features, the effect of printing curved parts using curved, conformal layers. These capabilities are combined to print an integrated demonstrator showing potential practical benefits of the system.

Orientation with respect to gravity has no effect on print quality; dynamically changing build orientation allows overhangs up to 90° to be cleanly printed without support structures; printing an arch with conformal layers significantly increases its strength compared to conventional printing.

The challenge of automatic slicing algorithms has not been addressed for multi-axis printing. It is shown that ARMS could eventually enable printing of fully-functional prototypes with embedded components.

This work is the first to prove that the surface roughness of an FFF part is independent of print orientation with respect to gravity. The use of two arms creates a novel system with more degrees of freedom than existing multi-axis printers, enabling studies on printing orientation relationships and printing around inserts. It also adds to the emerging body of multi-axis literature by verifying that curved layers improve the strength of an arch which is steeply curved and printed with the nozzle remaining normal to the curvature.

In Mali, dairy processors mostly use imported powdered milk rather than local fresh milk, constraining the development of a domestic milk sector. We investigate factors motivating a firm's choice of milk input, to identify measures that can encourage demand for fresh milk.

We utilize case study data from nine firms that use fresh and powdered milk to varying degrees, and which are representative of dairy processing in Bamako. To model firm motivations, we assess how each input contributes to or detracts from firm competitive advantage, through its influence on cost and differentiation.

Firms using fresh milk pay a higher input price, incur higher transaction costs and face additional challenges in production and distribution. Firms distinguish themselves from competitors through four potential sources of differentiation: novel product types, quality enhancements, quality-signaling and unique packaging. However, fresh milk firms are less likely to exploit each source of differentiation.

Competitive advantage is a useful framework for understanding firm behavior in developing markets and can be applied in other contexts to strengthen external validity.

The extant economics literature on African dairy development has been surprisingly silent on the threat of import competition. This research is one of the first to investigate this issue in the under-studied middle segment of food value chains.

This paper aims to explore the development of the accountability ideals and practices of Quaker industrialists during the period 1840–1914.

The research employs a case study approach and draws on the extensive archives of Quaker industrialists in the Richardson family networks, British Parliamentary Papers and the Religious Society of Friends together with relevant contemporary and current literature.

Friends shed their position as Enemies of the State and obtained status and accountabilities undifferentiated from those of non-Quakers. The reciprocal influences of an increasingly complex business environment and radical changes in religious beliefs and practices combined to shift accountabilities from the Quaker Meeting House to newly established legal accountability mechanisms. Static Quaker organisation structures and accountability processes were ineffective in a rapidly changing world. Decision-making was susceptible to the domination of the large Richardson family networks in the Newcastle Meeting House. This research found no evidence of Quaker corporate social accountability through action in the Richardson family networks and it questions the validity of this concept. The motivations underlying Quakers’ personal philanthropy and social activism were multiple and complex, extending far beyond accountabilities driven by religious belief.

This research has originality and value as a study of continuity and change in Quaker accountability regimes during a period that encompassed fundamental changes in Quakerism and its orthopraxy, and their business, social and political environments.

In this paper, I propose an algorithm combining adaptive sampling and Reversible Jump MCMC to deal with the problem of variable selection in time-varying linear model. These types of model arise naturally in financial application as illustrated by a motivational example. The methodology proposed here, dubbed adaptive reversible jump variable selection, differs from typical approaches by avoiding estimation of the factors and the difficulties stemming from the presence of the documented single factor bias. Illustrated by several simulated examples, the algorithm is shown to select the appropriate variables among a large set of candidates.

We contribute to the literature on institutional and organizational change by integrating two related areas of study: the theory and methods of analysis informed by the research on institutional logics and historical-event sequencing. Institutional logics provide the theory to understand how the content of culture influences organizational change; historical-event sequencing reveals the underlying patterns of cultural transformation. We apply this dual perspective to the cases of institutional stability and change in organizational governance in three industries: accounting, architecture, and higher-education publishing. Research on governance has focused on changes in organizational design between markets, hierarchies, and networks. Missing from this research is an understanding of how institutions at the wider societal level motivate organizations to adopt one of these governance forms over another. We examine how the governance of firms in these industries has been influenced by the institutional logics of the professions, the market, the state, and the corporation by focusing on three mechanisms – institutional entrepreneurs, structural overlap, and historical-event sequencing. Overall, our findings reveal how accounting was influenced by state regulation producing a punctuated equilibrium model, architecture by professional duality producing a cyclical model, and publishing by market rationalization producing an evolutionary model of institutional change in organizational governance.

In this chapter, the authors define the new business term, future-proofing, and apply it to knowledge preservation and curation. The fundamental principles of future-proofing and the challenges and mechanics are discussed. These challenges are discussed in developing future-proofed knowledge preservation, and a curation strategy is identified. The authors identify four challenges to future-proofing a knowledge preservation and curation strategy – availability, visibility, accessibility, and consumability of knowledge assets. Ultimately, the greatest challenge to future-proofing these strategies lies in the channels we use to create, transmit, share, and store knowledge assets. At a minimum, the chapter speaks to the critical importance of future-proofing the preservation of knowledge assets, so there is a possibility of curation at some point in a known or unknown future.

It is possible to say that an expert in any field of knowledge can be expected to know particular things and techniques. This can be said of a stone mason, a physicist or a midwife. The expertise consists of a notional core of knowledge and skills (i.e. applied knowledge). Such expertise arguably can be found in other experts in the same field, although there will be idiosyncrasies of approach and valuation and quite probably divergencies in what is considered “right” and “wrong”.

This chapter examines how hospitality and tourism researchers can use ‘expressive text’ (or writing) to express the lived quality of an experience in order to ‘show what an experience is really like’ rather than ‘tell what it is like’. Expressive text refers to written language forms such as narrative, poetry and metaphor that can be used as tools in research to vividly represent the meaning and feeling conveyed in an experience. The expressive text-based approach to researching lived experience provides a textual link between experience and its expression. For this reason, it is especially useful when working with lived experience accounts of phenomenological and hermeneutic research.

The expressive text-based approach suggested here is still a relatively under explored arena within hospitality and tourism research. As a relatively under explored arena, the rich insightful knowledge that can be gained from understanding practitioner experience is rarely a central focus of scholarly writings about the workplace in hospitality and tourism contexts. However, in order to be fully appreciated as a discipline in its own right and to advance knowledge of the field, understanding the typical and significant attributes of hospitality and tourism work will be decidedly helpful.

One of the difficulties of working with lived experience accounts is finding a suitable research approach that helps to both retain the lived elements of the experience and ensure the rigour of the inquiry. An expressive text-based methodological framework that has a phenomenological and hermeneutic philosophical underpinning is argued to be suitable for this purpose. Therefore, the focus of this study is to discuss such a methodology and explain the reasons for its content, style and structure in researching lived experience. The approach that is proposed here consists of a five-tiered textually expressive methodology that is employed to contextualise, portray and interpret the lived experience meanings in order to understand the significance of the experience in relation to relevant discourses in hospitality and tourism studies, and to consider implications for policy and professional practice. The guiding questions of the five-tiered framework cover the following issues: (1) What is the context of the lived experience? (2) What is the lived experience of this practice like? (3) What is the meaning of this experience for the practitioner? (4) What is the significance of the experience in contributing to the advancement of knowledge within the field? (5) What are the implications for practice and professional development?

To illustrate uses of this methodology in research, the study here includes an example showing portrayals and interpretations of the typical and significant lived nature of hospitality reception work. This shows and communicates the full meaning of the episode, circumstances or situation. The chapter then concludes with some reflections on benefits as well as tensions in working within an expressive text-based phenomenological and hermeneutic framework.

I don’t remember exactly when I began to be interested in music, but my mother and godmother would laughingly recall when they knew I would be musically inclined. Though I was then in diapers, whenever Tommy Dorsey's recording of Boogie Woogie was played, I would immediately begin to pat my feet. My first conscious memory of reacting to music when I was very young were the times my father would sing little ditties and play his banjo. He could carry a tune, and he played the banjo quite well. His greatest musical feat, however, was as a whistler, and I would try to imitate his whistling style, without success as I grew older. Then too, my siblings and I would sing and recite little nursery rhymes before our parents, and I would compose songs for my sisters to sing. Before he died an early death at 37 my father gave me a mouth harp and a harmonica which I kept for many years; I later misplaced it while in college. I later bought another harmonica which I kept throughout my years in the U.S. Army, my travels throughout Europe, and throughout my years in graduate school. How and why we each possess the talents and skills we have are questions I’ve never fully understood. So I’ve concluded that we just have them, and we’ll never be able to explain it. Throughout this chapter four reference points will be used to explain my exposure to music and my music biculturality: schools, churches, home, and my neighborhood. If I make very few references to whites, it is simply because during my early life my contact with whites was minimal, and white individuals played a minor role in my life, as at home my world centered around my parents and godparents, siblings, and other family members, and neighborhood friends; at school my world was a completely black world. The first white I got to know outside of my early work experiences was the white Presiding Bishop of the Reformed Episcopal Church who visited St. John's Episcopal Church at least six or seven times a year.
