Structure And Design

Purpose This paper aims to reveal the authors’ conceptual and experimental work on an innovative avionics paradigm for small unmanned aerial vehicles (UAVs). Design/methodology/approach This novel approach stipulates that, rather than being centralized at the autopilot, control of avionics devices is instead distributed among controllers – spread over the airframe span, in response to avionics devices’ natural location requirements. The latter controllers are herein referred to as edge controllers by the first author. Findings The edge controller manifests increased efficiency in a number of functions, some of which are unburdened from the autopilot. The edge controller establishes a new paradigm of structure and design of small UAVs avionics such that any functionality related to the periphery of the airframe is implemented in the controller. Research limitations/implications The research encompasses a workbench prototype testing on a breadboard, as the presented idea is a novel concept. Further, another test has been conducted with four controllers mounted on a quadcopter; results from the vertical attitude sustenance are disclosed herein. Practical implications The motivation behind developing this paradigm was the need to position certain avionics devices at different locations on the airframe. Due to their inherent functional requirements, most of these devices have hitherto been placed at the periphery of the aircraft construction. Originality/value The current paper describes the novel avionics paradigm, compares it to the standard approach and further reveals two experimental setups with testing results.

Purpose – The purpose of this paper is to investigate the generating capability of a novel hybrid excited brushless claw pole alternator (HEBCPA) with improved cost-effectiveness gained thanks to the substitution the rotor NdFeB-made permanent magnet (PM) with ferrite ones. Design/methodology/approach – The investigation of the magnetic features of the novel HEBCPA has been carried out using a 3D finite element analysis (FEA). Findings – It has been found that the machine generating capability is not affected by the substitution of the single rotor NdFeB-made PM by stator and rotor ferrite-made ones, which represents a crucial cost benefit. Research limitations/implications – An experimental validation of the features computed by FEA shall be considered as an outlook of the present work. Practical implications – The novel HEBCPA could be of great interest for automotive generating systems. Originality/value – The proposed HEBCPA with ferrite-made PMs is a novel concept.

Purpose The popular “beer game” illustrates the bullwhip effect where a small perturbation in downstream demand can create wild swings in upstream product flows. The purpose of this paper is to present a methodical framework to measure the bullwhip effect and evaluate its impact. Design/methodology/approach This paper illustrates a framework using SKU-level data from an industry-leading manufacturer, its distributors, end-users and suppliers. Findings Firms benefit from tracking multiple intra-firm bullwhips and from tracking bullwhips pertinent to specific products, specific suppliers and specific customers. The framework presented in this paper enables managers to pinpoint bullwhip sources and mitigate bullwhip effects. Research limitations/implications This paper presents a framework for methodically measuring and tracking intra-firm and inter-firm bullwhips. Practical implications A disconnect exists between what is known and taught regarding the bullwhip effect and how it is actually tracked and managed in practice. This paper aims to reduce this gap. For the various products analyzed herein, the authors show how using this framework has the potential to reduce delivered product cost by 2 to 15 per cent. Social implications Properly managing the bullwhip leads to lower inventories and potentially lower product prices while simultaneously increasing firm profits. Originality/value This paper presents a novel approach to systematically tracking intra-firm bullwhips along with bullwhips specific to a given supplier or customer.

Purpose The purpose of this paper is to report on research that aims to make knowledge, and in particular know-how, more easily accessible to both academic and industrial communities, as well as to the general public. The paper proposes a novel approach to map out know-how information, so all knowledge stakeholders are able to contribute to the knowledge and expertise accumulation, as well as using that knowledge for research and applying expertise to address problems. Design/methodology/approach This research followed a design science approach in which mapping of the know-how information was done by the research team and then tested with graduate students. During this research, the mapping approach was continuously evaluated and refined, and mapping guidelines and a prototype tool were developed. Findings Following an evaluation with graduate students, it was found that the know-how maps produced were easy to follow, allowed continuous evolution, facilitated easy modification through provided modularity capabilities, further supported reasoning about know-how and overall provided adequate expressiveness. Furthermore, we applied the approach with various domains and found that it was a good fit for its purpose across different knowledge domains. Practical implications This paper argues that mapping out know-how within research and industry communities can further improve resource (knowledge) utilization, reduce the phenomena of “re-inventing the wheel” and further create linkage across communities. Originality/value With the qualities mentioned above, know-how maps can both ease and support the increase of access to expert knowledge to various communities, and thus, promote re-use and expansion of knowledge for various purposes. Having an explicit representation of know-how further encourages innovation, as knowledge from various domains can be mapped, searched and reasoned, and gaps can be identified and filled.

Purpose This paper aims to evaluate the possibilities associated with go-along technique and other mobile qualitative methods augmenting other qualitative methods as a novel approach to developing understanding of multifaceted organisations. Design/methodology/approach The study explores the challenges associated with “static” qualitative methods for understanding multifaceted organisations and evaluates how a range of mobile methods can achieve a greater depth of analysis when researching complex hospitality and tourism settings. The paper uses an illustrative empirical case where mobile methods are used as part of a multi-method qualitative study exploring ancestral tourism in a large, heterogeneous tourism organisation. Findings This research highlights how mobile methods can service to: broaden the scope of interviews through introducing enhanced meaning and spontaneity; afford opportunity to explore and verify interview findings in informal settings; and widen participation in the study through ongoing recruitment of participants. Practical implications The authors identify implications for researchers working within hospitality and tourism who can gain additional insight by augmenting qualitative studies with mobile methods. Originality/value This paper identifies challenges in using more static qualitative methods when seeking understanding of complex, multifaceted tourism organisations where work activities are mobile and spatially dispersed. This research highlights the value of mobile methods in combination with other qualitative methods, to gain greater understanding of these organisations.

Purpose The purpose of this paper is to look at corporate social responsibility (CSR)-related actions to see whether they relate to clients’ perception of CSR. Design/methodology/approach Ninety-nine bank customers in Brisbane, Australia were surveyed by mail in a cross-sectional field study. Findings Not all CSR-related behaviors of the organizations were influential to perceptions of social responsibility. Big picture actions for the betterment of humanity were found to be influential to the perception of the firm’s CSR. However, respondents did not relate the firms’ profit and revenue initiatives to social responsibility, other than negativity toward false and misleading practices. Research limitations/implications Results are limited to one industry in Australia. Practical implications Actions for human betterment were found to be influential to the perception of the firm’s CSR. Also the uses of dishonest marketing schemes were seen as detrimental to CSR perceptions of the firm. However, respondents did not connect the firm’s business actions affecting profitability with customers, to their perceptions of its CSR. Thus, the authors conclude that altruism from a “big picture” standpoint has value in shaping CSR perception, but the organization may not always find it necessary to deprioritize profit, or to attempt to weave CSR actions into every aspect of their business. Originality/value The inquiry takes a novel approach to CSR, capturing an unexplored aspect of how CSR is perceived and valued by stakeholders.

Purpose This study aims to demonstrate the suitability of text-mining toolset for the discovery of trends in quality management (QM) literature in 2000-2019. The hypothesis was formulated that as the field of study is mature, the most important trends are related to deepening and broadening of the knowledge. Design/methodology/approach A novel approach to trend discovery was proposed. The computer-aided analysis of full-texts of papers led to increased reliability and level of detail of the achieved results and helped significantly reduce researchers’ bias. Overall, 4,833 papers from 8 journal dedicated to QM were analysed. Findings Trends discovery led to the identification of 45 trends: 17 long-lasting trends, 4 declining trends, 11 emerging trends and 13 ephemeris trends. They were compared to the results of earlier studies. New trends and potential gaps were discussed. Practical implications The results highlight the trends that gain or lose popularity, thus they can be used to focus studies, as well as find new subjects, which are not so popular yet. The knowledge about emerging trends is also important for those quality managers who strive for improvement of their efficiency. Originality/value The research was designed to bypass the limitations of previous studies. The use of text mining methods and analysis of full texts of papers delivered more detailed and reliable data. Resignation from predefinition of classification criteria significantly reduced researchers’ bias and allowed the discovery of new trends, not identified in previous studies.

Purpose On 12 November 2018, New Zealand's Land Transfer Act 2017 came into force. The purpose of this paper is to pinpoint some of the significant changes in the Act that challenge the fundamental concepts of the Torrens system of registration. Design/methodology/approach The paper addresses three significant reforms: a definition of land transfer fraud; the concept of immediate indefeasibility with limited judicial discretion and its impact on volunteers and the Gibbs v. Messer anomaly; and the compensation regime. Case studies illustrate the effect of these changes. Findings The limited legislative definition of fraud reflects the common law and allows for any necessary flexibility. The new Act reiterates the principle of immediate indefeasibility but qualifies it with the introduction of some judicial discretion. This is a novel concept for the courts and will undoubtedly be dealt with cautiously. The author voices some disquiet with regard to some of the guidelines set out in s 55(4) of the Act. The compensation provisions introduce an element of an owner's culpability. An owner now runs the risk of reduced compensation if there has been a lack of proper care. Research limitations/implications The implications of this research are fundamental for New Zealand's land transfer system. Practical implications The limited judicial discretion will challenge the courts of New Zealand. The new compensation provisions will ensure that an owner's carelessness will be accountable. Originality/value This study is one of the first to analyse the Land Transfer Act 2017 (New Zealand). Its value extends beyond New Zealand shores as it has implications for global land transfer systems.

PurposeThis article considers the possibilities of and barriers to socialising tourism after the coronavirus disease 2019 (COVID-19) pandemic. Such an approach allows us to transform tourism and thereby evolve it to be of wider benefit and less damaging to societies and ecologies than has been the case under the corporatised model of tourism.Design/methodology/approachThis conceptual analysis draws on the theorisation of “tourism as a social force” and the new concept of “socialising tourism”. Using critical tourism approaches, it seeks to identify the dynamics that are evident in order to assess the possibilities for socialising tourism for social and ecological justice. It employs an Indigenous perspective that the past, present and future are interconnected in its consideration of tourism futures.FindingsCOVID-19 has fundamentally disrupted tourism, travel and affiliated industries. In dealing with the crisis, borders have been shut, lockdowns imposed and international tourism curtailed. The pandemic foregrounded the renewal of social bonds and social capacities as governments acted to prevent economic and social devastation. This disruption of normality has inspired some to envision radical transformations in tourism to address the injustices and unsustainability of tourism. Others remain sceptical of the likelihood of transformation. Indeed, phenomena such as vaccine privilege and vaccine tourism are indicators that transformations must be enabled. The authors look to New Zealand examples as hopeful indications of the ways in which tourism might be transformed for social and ecological justice.Practical implicationsThis conceptualisation could guide the industry to better stakeholder relations and sustainability.Social implicationsSocialising tourism offers a fruitful pathway to rethinking tourism through a reorientation of the social relations it fosters and thereby transforming its social impacts for the better.Originality/valueThis work engages with the novel concept of “socialising tourism”. In connecting this new theory to the older theory of “tourism as a social force”, this paper considers how COVID-19 has offered a possible transformative moment to enable more just and sustainable tourism futures.
