IT is impossible to obtain accurate information on the cost of aircraft corrosion to the civil airline operators and the armed services. The true cost should include aircraft washing and cleaning, the cost of inspection, the application of supplementary protectives and maintenance of the protective scheme as well as the cost of blending out corrosion damage and the replacement of parts which cannot be repaired. The removal of paint and repainting are further items which must be included in the overall corrosion costs. Estimates made by IATA in 1982 suggested that member airlines were spending the order of 200 million dollars per year on corrosion rectification or the equivalent of 8 to 20 dollars per flying hour depending on the aircraft type or operator. More recently it has been suggested that the actual cost of corrosion to the USAF is probably about one billion dollars per year.

This study aims to improve the buying experience for both customers and providers by presenting a conceptual basis which seeks to expand the usual understanding, representation, mapping and measurements of the different value and non-value stages of a customer purchase journey (CPJ).

Inspired by the precepts of lean thinking, with emphasis on the value stream mapping method, the approach is based on an in-depth analysis of a real and typical e-commerce acquisition of an electronic customised product (a mobile phone) during the COVID-19 pandemic.

This study demonstrates different types of consumer stages, values and wastes for the CPJ. This allowed the development of a mathematical formulation – named customer journey engineering (CJE) – from which improvements of the different categories can be identified. Exemplifying with those whose implementations require no further efforts or costs, the following results could be readily obtained in the case studied: a reduction of 96 h of non-value activities, an improvement of approximately 15% of the established index for customer satisfaction and avoidance of loss worth US$50 for the analysed customer.

The consistency and applicability of the qualitative and quantitative findings presented here should be examined further in other customer purchase scenarios, allowing enhancements of the CJE approach.

Regardless of the context in question, this investigation attempts to identify and precisely define any common universal elements, often overlooked, which constitute the structure of any CPJ and are crucial for its understanding and improvement.

Resurgent interest in the life and work of the Italian Cambridge economist Piero Sraffa is leading to New Directions in Sraffa Scholarship. This chapter introduces readers to some of these developments. First and perhaps foremost is the fact that as of September 2016 Sraffa’s archival material has been uploaded onto the website of the Wren Library, Trinity College, Cambridge University, as digital colour images; this chapter introduces readers to the history of these events. This history provides sharp relief on the extant debates over the role of the archival material in leading to the final publication of Production of Commodities by Means of Commodities, and readers are provided a brief sketch of these matters. The varied nature of Sraffa scholarship is demonstrated by the different aspects of Sraffa’s intellectual legacy which are developed and discussed in the various entries of our Symposium. The conclusion is reached that we are on the cusp of an exciting phase change of tremendous potential in Sraffa scholarship.

This paper provides a reappreciation of the second edition of Carl Menger’s Principles. It reconstructs his new theory of needs, which for Menger analytically precedes the valuation of goods. It is argued that this new theory of needs provides a possible bridge between economics and the natural sciences. It provided important conceptual tools for the interwar work of Ludwig von Mises on praxeology and Friedrich Hayek on expectations and plans. The new first chapter also contains a theory of collective needs, which is contextualized in the broader German-language debate over private and public provision of goods. It is demonstrated that Menger’s approach to collective needs, and the jointness of consumption is in tension with the later Samuelson/Musgrave conception of public goods, and compatible with the institutional theories in this field of James Buchanan and Vincent and Elinor Ostrom.

Laboratory studies of social interaction have revealed a wide range of phenomena that are difficult to explain using standard economic models. For example, people will often sacrifice their own earnings in order to be generous, cooperative, punitive, and retributive in interactions with anonymous strangers. “Behavioral” models that redefine agents’ preferences attempt to provide an account of these phenomena as reflecting a “taste for fairness” or altruism, aversion to inequality, concern about others’ beliefs, and so on. Such models either fail to account for the rich sensitivity of actions to context or in allowing for rich context-dependence, these models ultimately substitute description for explanation. Hayek’s work provides a foundation for thinking about how to explain these phenomena, by conceiving of people as both purpose-seeking (as in economic models) and rule-following. Decisions are shaped both by material interests and by a normative framework that is evoked by context and helps people decide what one ought to do in a particular situation. The implication of this approach is that rather than trying to understand heterogeneity across individuals in terms of preferences, experimenters should instead try to understand heterogeneity across contexts in terms of the rules and norms that operate in the background and guide or constrain people’s purpose-seeking tendencies. What economics needs, then, is a theory of how and why these rules and norms vary with context as they do.

The overall goal of science is to build a valid and reliable body of knowledge about the functioning of the world and how applying that knowledge can change it. As personnel and human resources management researchers, we aim to contribute to the respective bodies of knowledge to provide both employers and employees with a workable foundation to help with those problems they are confronted with. However, what research on research has consistently demonstrated is that the scientific endeavor possesses existential issues including a substantial lack of (a) solid theory, (b) replicability, (c) reproducibility, (d) proper and generalizable samples, (e) sufficient quality control (i.e., peer review), (f) robust and trustworthy statistical results, (g) availability of research, and (h) sufficient practical implications. In this chapter, we first sing a song of sorrow regarding the current state of the social sciences in general and personnel and human resources management specifically. Then, we investigate potential grievances that might have led to it (i.e., questionable research practices, misplaced incentives), only to end with a verse of hope by outlining an avenue for betterment (i.e., open science and policy changes at multiple levels).

Indigenous students that live in poverty experience contextual socio-economic factors with residual effects of lower educational outcomes than their non-Indigenous counterparts. Indigenous children that live in poverty often have fewer resources, are segregated, and continue to be marginalized in the classroom. The vicious cycle of low education levels for Indigenous peoples confines them to low paying employment or unemployment that results in ongoing poverty or being a statistic categorized as the working poor. The purpose of this research was to gain a better understanding of the strategies that teachers have animated in their classrooms, which they perceived to be successful in encouraging Indigenous students to attend school, remain in school, complete course credits, and persevere to graduate from high school. The intent was to discover the how-to strategies and advance working knowledge of pedagogical practices leading to improved educational experiences and achievement levels for Indigenous students. This chapter will present the observations and qualitative findings of the case studies conducted in New Zealand and Canada, wherein 14 teachers described what they did and what it looked like in their classrooms. A constructivist approach was utilized to make meaning and gain the interpretations from the participants. This was achieved by first viewing the interactions in the classrooms and, through the interview process, being able to garner a better understanding of what was witnessed from the point of view of the participants.

In this comparative study, we explore the ways eight queer university students from Trinidad and Tobago and New Brunswick, Canada, use cellphilm production (cellphone + film production + intention) to share their experiences, make calls for change, and forge solidarities across racial, cultural, and national contexts. Engaging in cellphilm production as a research method for social change, we ask: What are queer, trans, and non-binary students’ experiences in campus spaces? What are the commonalities and tensions that exist between their experiences? How might cellphilm production work to disrupt unsafe campus spaces and create transnational queer solidarities? Through cellphilm production, participants crafted narratives highlighting significant systemic barriers, and speaking back to micro and macro aggressions. Both participating groups expressed feelings of exclusion and institutional neglect and highlighted their university’s disregard toward accommodating physical spaces, such as washrooms, downplaying of verbal hostilities, and other microaggressions. Participants also noted that students were at the forefront of creating purposefully queer spaces. Our comparative study disrupts the erasure of the experiences of queer, trans, and non-binary university students in Trinidad and Tobago and New Brunswick and speaks back to hegemonic whiteness in the context of queer campus spaces in New Brunswick, Canada.

Philosophers and political theorists have long warned of the “perils of dogmatism” for public discourse and identified intellectual humility as a necessary corrective. Sufficient intellectual humility encompasses at least four elements: openness to error, recognition of bias, recognition of intellectual parity in interlocutors, and avoidance of recourse to authority. Religions seem to present obstacles on all four fronts, particularly when actors embody more conservative renderings of a given religion’s repertoire. As such, a case involving different groups of religious exclusivists engaging one another on topics that directly interact their deepest faith commitments and political visions presents a useful test case for our theories of intellectual humility. This chapter considers conservative protestants engaging in public discourse with Muslims about whether or not Muslim and Christian understandings of “loving God” and “loving neighbor” have sufficient overlap to support political cooperation. The results of the dialogue effort were a mixture of controversy and cooperation. For evangelicals, the engagement produced sharp conflict and yet helped to shift the community’s plausibility structures, opening further the possibility of fruitful public discourse and strategic action in cooperation with Muslims. The analysis suggests a conceptualization of practical intellectual humility that emphasizes recognition of the other.
