Abstract

Health risks associated with coronavirus disease 2019 (COVID-19) have severely affected the financial stability of airline companies globally. Recapturing financial stability following this crisis depends heavily on these companies’ ability to attain efficient and productive operations. This study uses several empirical approaches to examine key factors contributing to carriers sustaining high productivity prior to, during and after a major recession. Findings suggest, regardless of economic conditions, that social distancing which requires airline companies in the Asia Pacific region to fly with a significant percentage of unfilled seats weakens the performance of those companies. Furthermore, efficient operations do not guarantee the avoidance of productivity declines, especially during a recession.

Abstract

Purpose

The purpose of this study is to propose a new method for the end-to-end classification of steel surface defects.

Design/methodology/approach

This study proposes an AM-AoN-SNN algorithm, which combines an attention mechanism (AM) with an All-optical Neuron-based spiking neural network (AoN-SNN). The AM enhances network learning and extracts defective features, while the AoN-SNN predicts both the labels of the defects and the final labels of the images. Compared to the conventional Leaky-Integrated and Fire SNN, the AoN-SNN has improved the activation of neurons.

Findings

The experimental findings on Northeast University (NEU)-CLS demonstrate that the proposed neural network detection approach outperforms other methods. Furthermore, the network’s effectiveness was tested, and the results indicate that the proposed method can achieve high detection accuracy and strong anti-interference capabilities while maintaining a basic structure.

Originality/value

This study introduces a novel approach to classifying steel surface defects using a combination of a shallow AoN-SNN and a hybrid AM with different network architectures. The proposed method is the first study of SNN networks applied to this task.

Abstract

This study examined the factors influencing willingness-to-repurchase for each class of airline service, and integrate the constructs of service quality, satisfaction and willingness-to-repurchase which were rooted on Engel-Kollat-Blackwell (EKB) model. The study focuses on the domestic and international arrival of passengers at Murtala Muhammed International Airport in Lagos and Nnamdi Azikwe International Airport in Abuja. Information was gathered from domestic and foreign passengers who had post-purchase experience and had used the airline's services more than once. The survey data were obtained concurrently from arrival passengers at two major international airports using an electronic questionnaire through random and purposive sampling techniques. The data was analysed using the ordinal logit model and structural equation model. From the 606 respondents, 524 responses were received but 489 responses were valid for data analysis and reporting and were obtained mostly from economy and business class passengers. The study found that the quality of seat pitch, allowance of 30 kg luggage permission, availability of online check-in 24 hours before the departing flight, quality of space for legroom between seats, and the quality of seats that can be converted into a fully flatbed are the major service factors influencing willingness-to-repurchase economy and business class tickets. Also, it was found that passengers' willingness to repurchase is influenced majorly by service quality, but not necessarily influenced by satisfaction. These results reflect the passengers' consciousness of COVID-19 because the study was conducted during the heat of COVID-19 pandemic. Recommendations were suggested for airline management based on each class.

Abstract

The COVID-19 pandemic provides an opportunity to review net neutrality and the notion that bright light rules are necessary to hold broadband providers from exercising market power. The 2015 Federal Communications Commission (FCC) Open Internet Order asserted that broadband providers have the capability and incentive to harm their customers and third-party service providers. It imposed a set of rules to control broadband providers’ offers, prices, and traffic management. The 2017 FCC vacated all but the transparency provisions of the OIO, restoring the oversight of broadband to the FTC.

This paper offers a review of the evidence regarding the effects of net neutrality regulation, including an investigation of the incidence of violations, or lack thereof, during the 2020 pandemic in the United States. It provides a review of the net neutrality literature and the international research on broadband provider behaviour during COVID-19. The paper presents original research conducted with FCC and FTC reports and a survey of news stories. Brief reviews of federal data on network performance and broadband adoption provide additional context. Given the limited incidence of violations that could be uncovered for the period, the paper suggests why broadband providers behaved opposite to regulatory advocates’ predictions. Contrary to many policy assertions, broadband providers did not block or throttle service, nor did they increase prices arbitrarily or decrease quality. Broadband providers appeared to expand availability, lower broadband prices, and make more networks available, frequently without customer charge. The paper suggests how policy could be updated to reflect the actual behaviour of broadband providers.

Abstract

Over the past decade, criminology in Australia, Canada and other settler colonies has increasingly engaged with activist challenges to the penal system. These anti-carceral engagements have been levelled at its laws, institutions and agents. Following a long history of criminology explicating and buttressing penal institutions, the criminological gaze slowly transitioned in the 1970s to a more critical lens, shifting focus from the people who are criminalised to the harms of the apparatus that criminalises. However, the focus remained steadfastly on institutions and dominant players – until much more recently. The COVID-19 pandemic has revealed the strength of activist organisations and grassroots movements in affecting change and shaping debates in relation to the penal system. This chapter will explore the role of activism in informing criminological scholarship during the pandemic period and how criminologists, in turn, have increasingly recognised the need to build alliances and collaborations with grassroots activists and engage in their own activism. The chapter focuses primarily on Australian and Canadian criminology and its growing imbrication with the prison abolition movement, especially in the shadow of ongoing colonial violence. It considers how activist scholars, including ourselves, attempt to build movements for structural change in the criminal system and beyond.

Abstract

Purpose

The main objective of this paper is to provide a systematic literature review (SLR) and structured insight into last mile delivery, ultimately identifying gaps in current knowledge and proposing a framework for future research direction in terms of sustainability in the area.

Design/methodology/approach

This paper identifies and synthesizes information from academic journals and examines “Journals and Publishing place,” “Geographic location,” “Year of Publication,” “University and Author Affiliation,” “Themes and Sub-themes,” “Theory,” “Research Design, Methods and Area” and “Industry Involvement.” A collection of online databases from 2005 to 2020 were explored, using the keywords “Last mile delivery,” “Last mile logistics,” “Last mile transportation,” “Last mile fulfillment,” “Last mile operations” and “Last mile distribution” in their title and/or abstract and/or keywords. Accordingly, a total of 281 journal articles were found in this discipline area, and data were derived from a succession of variables.

Findings

There has been significant growth in published articles concerning last mile delivery over the last 15 years (2005–2020). An in-depth review of the literature shows five dimensions of the last mile: last mile delivery, transportation, operations, distribution and logistics. Each of these dimensions is interrelated and possess clustered characteristics. For instance, last mile operations, last mile transportation and last mile delivery are operational, whereas last mile distribution is tactical, and last mile logistics possess strategic characteristics. The findings also indicate that even though the sustainability concept can be incorporated into all levels of the last mile, the current literature landscape mainly concentrates on the operational level.

Research limitations/implications

This review is limited to academic sources available from Emerald Insight, Science Direct, Taylor and Francis, Springer, MDPI and IEEE containing the mentioned keywords in the title and/or abstract/or keywords. Furthermore, only papers from high-quality, peer-reviewed journals were evaluated. Other sources such as books and conference papers were not included.

Practical implications

This study dissects last mile delivery to produce a framework that captures and presents its complex characteristics and its interconnectedness with various related components. By analyzing last mile delivery in its entirety, the framework also helps practitioners pinpoint which levels of last mile delivery (operation, tactical or strategic) they can incorporate the concept of sustainability.

Originality/value

The research findings enrich the contemporary literature landscape and future work by providing a conceptual framework that incorporates the “economic,” “environmental” and “social” pillars of sustainability in all dimensions of the last mile delivery.

Abstract

The American agricultural economist Marion Clawson advised the Israeli government during 1953–1955. Clawson, a protégé of John D. Black and Mordecai Ezekiel, criticized the government for ignoring economic considerations, and stated that Israel’s national goals – defense, Negev Desert irrigation, immigrant absorption via new agricultural settlements, and economic independence – were mutually contradictory. His major recommendations were to improve the realism of Israel’s agricultural plan; end expensive Negev irrigation; enlarge irrigated farms eightfold; freeze new settlements until the number of semi-developed settlements falls from 300 to 100; and limit new Negev settlements to 10 over 5–7 years. Thus, Clawson ignored political feasibility and made value judgments. Minister of Finance Levi Eshkol and Minister of Agriculture Peretz Naphtali rejected Clawson’s recommendations because they ignored Israel’s national goals. By September 1954, Clawson shifted towards greater pragmatism: He acknowledged that foreign advisors should not question the national goals or make value judgments, and sought common ground with the Ministry of Agriculture. At his initiative, he wrote Israel Agriculture 1953/54 in collaboration with the Ministry of Agriculture. Israel Agriculture was a consensus document: Clawson eschewed recommendations and accepted that the government might prioritize non-economic goals. In proposing Israel Agriculture, Clawson made a pragmatic decision to relinquish some independence for (potentially) greater influence. Ultimately, Clawson was largely unsuccessful as an advisor. Clawson’s failure was part of a general pattern: Over 1950–1985, the Israeli government always rejected foreign advisors’ recommendations unless it was facing a severe crisis.

Abstract

Purpose

There is an increasing trend of outsourcing maintenance activities of heavy equipment, including belt conveyor installations. However, there are numerous challenges in maintenance outsourcing. This paper aims to identify and analyze various challenges of outsourcing maintenance activities associated with belt conveyor installations.

Design/methodology/approach

This paper identifies maintenance outsourcing challenges of belt conveyor installations through literature review, field visits and expert opinion. An integrated structural hierarchical framework of the identified challenges is developed through analytic hierarchy process and decision-making trial and evaluation laboratory.

Findings

The paper has identified eight challenges, namely, attainment of organizational strength by contractors, legal and financial challenges for contractors, attainment of necessary technician skills by contractors, maintenance data acquisition and analysis challenges, facilitation with modern equipment, gadgets and instrumentation, service quality challenges, health, safety and environment-related challenges and spares supply chain management challenges. The segregation of driver and dependent challenges, including their hierarchical framework had been established in this work.

Research limitations/implications

A comprehensive list of challenges and their prioritization in maintenance outsourcing of belt conveyor installations had been established. This will help the organizations who own and operate these installations to make judicious decisions regarding outsourcing maintenance.

Originality/value

This paper significantly contributes to the literature on maintenance outsourcing of heavy machinery installations like a belt conveyor system based on the input of different stakeholders. This study will lead to the development of frameworks for maintenance contractor selection for such installations.

Abstract

Purpose

Supporting distant teams is a frequent phenomenon. Through the lens of the social identity theory, this research aims to examine differences between local and distant fans regarding drivers of team identification.

Design/methodology/approach

A multigroup structural equation model was employed. The data were collected through an online survey with 1,285 sports fans.

Findings

Team distinctiveness constitutes an important aspect fueling identification for all fans, whereas congruence between own and team personality is important for local and displaced fans only. Team prestige does not impact identification for either group.

Practical implications

To build up a base of highly identified supporters, clubs should emphasize those aspects of team brands that fans consider distinctive. When targeting local fans, clubs should also focus on communicating the brand's unique personality aspects.

Originality/value

This is the first study that assesses the potential differences behind fans' social identification with local and distant teams.
