Abstract
Purpose
The study aims to investigate the impact of additive manufacturing (AM) on the performance of a spare parts supply chain with a particular focus on underlying spare part demand patterns.
Design/methodology/approach
This work evaluates various AM-enabled supply chain configurations through Monte Carlo simulation. Historical demand simulation and intermittent demand forecasting are used in conjunction with a mixed integer linear program to determine optimal network nodal inventory policies. By varying demand characteristics and AM capacity this work assesses how to best employ AM capability within the network.
Findings
This research assesses the preferred AM-enabled supply chain configuration for varying levels of intermittent demand patterns and AM production capacity. The research shows that variation in demand patterns alone directly affects the preferred network configuration. The relationship between the demand volume and relative AM production capacity affects the regions of superior network configuration performance.
Research limitations/implications
This research makes several simplifying assumptions regarding AM technical capabilities. AM production time is assumed to be deterministic and does not consider build failure probability, build chamber capacity, part size, part complexity and post-processing requirements.
Originality/value
This research is the first study to link realistic spare part demand characterization to AM supply chain design using quantitative modeling.

Abstract
Purpose
The purpose of this paper is to investigate US noncombatant evacuation operations (NEO) in South Korea and devise planning and management procedures that improve the efficiency of those missions.
Design/methodology/approach
It formulates a time-staged network model of the South Korean noncombatant evacuation system as a mixed integer linear program to determine an optimal flow configuration that minimizes the time required to complete an evacuation. This solution considers the capacity and resource constraints of multiple transportation modes and effectively allocates the limited assets across a time-staged network to create a feasible evacuation plan. That solution is post-processed and a vehicle routing procedure then produces a high resolution schedule for each individual asset throughout the entire duration of the NEO.
Findings
This work makes a clear improvement in the decision-making and resource allocation methodology currently used in a NEO on the Korea peninsula. It immediately provides previously unidentifiable information regarding the scope and requirements of a particular evacuation scenario and then produces an executable schedule for assets to facilitate mission accomplishment.
Originality/value
The significance of this work is not relegated only to evacuation operations on the Korean peninsula; there are numerous other NEO and natural disaster related scenarios that can benefit from this approach.

Abstract
Purpose
The purpose of this paper is to propose a conceptual framework that highlights transhumanism’s ideals of achieving superintelligence, super longevity and super well-being through human enhancement technologies (HET) and their relations with services marketing principles.
Design/methodology/approach
Framed by the transformative service research (TSR), this conceptual work articulates the 7Ps of the marketing mix with four macro-factors that create tensions at both the marketplace and consumer levels.
Findings
HET has potential for doing good but also tremendous bad; greater attention is needed from services marketing researchers especially in one proprietary research area: bioethics.
Research limitations/implications
The authors contribute to the growing work on TSR investigating how the interplay between service providers and consumers affects the well-being of both. Additionally, the authors call for novel interdisciplinary work in transhuman services research.
Originality/value
To the best of the authors’ knowledge, this is one of the first papers in services marketing research to explore the promises and perils of transhumanism ideals and human enhancement technologies.

This article explores the childhood, professional life and social activism of Alice Rigney (1942–2017) who became Australia's first Aboriginal woman principal in 1986.
Abstract
Purpose
This article explores the childhood, professional life and social activism of Alice Rigney (1942–2017) who became Australia's first Aboriginal woman principal in 1986.
Design/methodology/approach
The article draws on interviews with Alice Rigney along with newspapers, education department correspondence and reports of relevant organisations which are read against the grain to elevate Aboriginal people's self-determination and agency.
Findings
The article illuminates Alice/Alitya Rigney's engagement with education and culture from her childhood to her work as an Aboriginal teacher aide, teacher, inaugural principal of Kaurna Plains Aboriginal school in Adelaide, South Australia; and her activism as a Narungga and Kaurna Elder. Furthermore, the article highlights her challenges to racial and gender discrimination in the state school system.
Originality/value
While there is an expanding body of historical research on Aboriginal students, this article focuses on the experiences of an Aboriginal educator which are also essential to deconstructing histories of Australian education.
