The current outbreak of COVID-19 is an unprecedented event in air transportation. In this study, we investigate the impact of COVID-19 on global air transportation through the lens of complex networks different at different scales, ranging from worldwide airport networks where airports are nodes and links between airports exist when direct flights exist, to international country networks where countries are contracted as nodes, and to domestic airport networks for representative countries/regions. We focus on the spatial-temporal evolutionary dynamics of COVID-19 in air transportation networks, discovering hidden patterns on flight frequency reduction. Our study provides a comprehensive empirical analysis on the impact of the COVID-19 pandemic on aviation from a complex system perspective.

This study attempts to figure out the factors that contributed to deposing certain elected presidents before the end of their constitutional terms, alongside tracing the new political context that prevailed in Latin America since 1978 and its impact on direct political participation and military behavior during presidential crises.

The paper uses the comparative method to investigate the causes of presidential instability in three case studies.

The likelihood of presidential instability increases when a president enacts austerity economic policies that marginalize large sectors of the citizenry, becomes implicated in acts of corruption and develops a hostile relationship with members of the ruling coalition.

This study integrates the social movement theory with analytical perspectives from parliamentary behavior to explain presidential instability. It attempts to investigate the dynamics of interaction between the acts of furious citizens and disloyal legislators through the in-depth analysis of three case studies.

This study aims to facilitate access to vascular disease screening for low-income individuals living in remote and conflict areas based on the results of a pilot trial in Colombia. Also, to increase the amount of diagnosis training of vascular surgery (VS) in civilians.

The operation method includes five stages: strategy development and adjustment; translation of the strategy into a real-world setting; operation logistics planning; strategy analysis and adoption. The operation plan worked efficiently in this study’s sample. It demonstrated high sensibility, efficiency and safety in a real-world setting.

The authors developed and implemented a flow model operating plan for screening vascular pathologies in low-income patients pro bono without proper access to vascular health care. A total of 140 patients from rural areas in Colombia were recruited to a controlled screening session where they underwent serial noninvasive ultrasound assessments conducted by health professionals of different training stages in VS.

The plan was designed to be implemented in remote, conflict areas with limited access to VS care. Vascular injuries are critically important and common among civilians and military forces in regions with active armed conflicts. As this strategy can be modified and adapted to different medical specialties and geographic areas, the authors recommend checking the related legislation and legal aspects of the intended areas where we will implement this tool.

Different sub-specialties can implement the described method to be translated into significant areas of medicine, as the authors can adjust the deployment and execution for the assessment in peripheral areas, conflict zones and other public health crises that require a faster response. This is necessary, as the amount of training to which VS trainees are exposed is low. A simulated exercise offers a novel opportunity to enhance their current diagnostic skills using ultrasound in a controlled environment.

Evaluating and assessing patients with limited access to vascular medicine and other specialties can decrease the burden of vascular disease and related complications and increase the number of treatments available for remote communities.

It is essential to assess the most significant number of patients and treat them according to their triage designation. This management is similar to assessment in remote areas without access to a proper VS consult. The authors were able to determine, classify and redirect to therapeutic interventions the patients with positive findings in remote areas with a fast deployment methodology in VS.

Access to health care is limited due to multiple barriers and the assessment and response, especially in peripheral areas that require a highly skilled team of medical professionals and related equipment. The authors tested a novel mobile assessment tool for remote and conflict areas in a rural zone of Colombia.

This paper aims to examine how long-lived firms can further develop through digitalisation in terms of actions, conditions and effects from a competitiveness perspective.

This exploratory study follows an inductive approach based on a survey conducted via interviews undertaken with nine long-lived Italian firms. The dimensions of the model (command, continuity, community, connection), elaborated by Miller and Le Breton-Miller (2005) in relation to longevity factors, were chosen to analyse digitalisation’s contribution to these long-lived firms’ development.

The digitalisation implemented by the analysed firms contributed in a variety of ways: (1) improved the efficiency and effectiveness of their business processes, (2) enhanced the understanding of customer experience, (3) supported their craftsmanship and the transmission of the knowledge included in the entrepreneurial path, (4) increased the awareness of the cultural value of the firms’ heritage and (5) allowed for the development of cutting-edge design skills by experimenting with content on different digital platforms and devices.

This study suggests managers of long-lived firms develop digital skills that allow them to interact with the rapid evolution of this context and understand how to effectively implement digitalisation in their specific firm. From this perspective, it is strategic to establish or strengthen collaborative network relationships to acquire such necessary skills.

This study provides novel empirical evidence on how long-lived firms are facing the challenge of digitalisation in terms of actions, conditions and effects to improve their competitiveness and ensure their survival.

This paper aims to study whether international niche market leaders (INMLs) gained their leading position as early mover or diligent follower, and assess whether they leveraged hard or soft forms of technological, supply pre-emption and customer lock-in advantage mechanisms.

Empirical material stems from qualitative and quantitative data on a sample of 20 niche companies from the Basque Country (Spain) that operate in business to business markets.

The sample predominantly followed an early entrant strategy and applied soft measures to reach niche market leadership.

Findings imply that early entering fosters conquering leadership in niche markets, that pioneer advantage is easier to sustain in niches than in mainstream markets, and that soft measures are more effective in niche markets than in larger markets. A limitation to our findings is that they follow from explorative research on a sample of firms from a reduced geographic setting.

Hidden champions and INMLs can be important sources of technological progress and economic value for the localities that host them. Therefore, despite their traditional low profile and the fact that they are not always the largest firms around, policymakers may want to pay more attention to this type of companies.

Tot he best of the authors’ knowledge, this is the first paper to research entry timing and its outcome for market leadership with regard to niche players or hidden champions-type of firms. It introduces an original taxonomy to operationalize and distinguish between hard and soft measures to leverage advantage mechanisms related to market entry timing.

The Spanish airport system contains several regional airports within an amenity distance and alternative travel modes. Profitable airports cross-subsidise small airports, which are not required for regional development or connectivity. Airports are government-owned and centralised-managed by Spanish Airports and Air Navigation (AENA, for its Spanish acronym). This study aims to analyse the probability of an under-used public infrastructure and the AENA’s managerial ability as per the financial sustainability of the network in the long term.

The national regulatory framework determines the airports’ environment. Six airports revealed unobserved heterogeneity, avoiding model misspecification. The framework is defined through proxies of the singularities of the Spanish framework: public investments and geographical specifications. The stochastic frontier analysis model follows two time-varying specifications, accounting for airports’ environmental factors, to ensure the robustness of the results to differ from the inefficiency caused by AENA and external factors.

Airports’ infrastructure capacity and traffic are not correlated; regional airports become a financial burden for the system unless they specialise or differentiate. Proxies defining the airports’ context are relevant. Because airports do not compete for airlines and passengers, there are too many regional airports with little traffic, resulting in disused public infrastructure that falls far short of improving connectivity and regional development.

This study contributes to paying attention to the characteristics of the regulatory framework, such as management strongly centralised in AENA, airport charges decided by the owner, lack of competition and lack of an independent regulatory entity. Another original contribution considers reliable capital measures (airports’ infrastructure).

This paper assesses the state and development of integrated thinking research in selected developed and developing economies by providing a “stock taking” of the literature included in the Scopus Database based on filtered criteria.

A search was performed on the Scopus Database and all sources containing “integrated thinking” in the title, abstract, or keywords were extracted. A total of 98 sources from 2011–2021 are analysed. These are coded with the support of a content analysis and a bibliometric analysis to determine research objectives and methods, affiliations, the locus of enquiry and epistemological perspectives.

There is a steady increase in attention devoted to integrated thinking research. The earliest studies were concerned primarily with the type of extra-financial information being included in an organisation's reports. This has given way to studies concerned with the operationalisation of integrated thinking. The current research has predominantly focussed on non-positivist epistemologies at the macro- and meso-levels with limited research undertaken at organisational levels.

Research on integrated thinking is particularly relevant in the context of developing economies where integrated thinking can be used as a means to value-creation, sustainable development and stakeholder inclusivity.

This paper provides a useful reference for practitioners, academics and journal editors interested in the development of integrated thinking research.

This paper highlights the need for more active research on integrated thinking and reporting in developing economies because much of what has been published to date comes from developed nations. This paper provides an overview of the state of integrated thinking research and presents important areas for future research.

This study aims at investigating the impact of using Lego Serious Play (LSP) on the effectiveness of teaching supply chain (SC) 4.0 in higher education by going from a traditional 2D approach to a 3D one. LSP in this study is explored as a gamification pedagogical approach that taps into the connection between hands and brain to inspire and engage students to build 3D models using metaphors and storytelling.

An empirical study was conducted among 50 students (over two terms) who were enrolled in a SC 4.0 course and used LSP in their final project that focused on digital SC design. Two questionnaires were designed (one after the standard LSP workshop and the other upon completion of the project) to solicit feedback with respect to how LSP helped students to better understand SC 4.0 topics and fulfill their project. The results were analyzed using Bloom’s taxonomy as well as other pedagogical framework to understand the positive impact of LSP at the cognitive, motivation and social levels.

Results showed that using LSP can enhance the teaching of various SC principles and technologies beyond the abstract point of view (2D) through offering the students an opportunity to apply these principles and technologies in a futuristic project using a hands-on 3D approach. The LSP approach demonstrated its ability to help students navigate through both lower order thinking skills (LOTS) and higher order thinking skills (HOTS) in a meaningful and playful manner. Finally, improving the design skills for students was clear using LSP as it unleashes imagination and taps into internal knowledge together with collective inputs.

The reliance on one case study can be a limitation regarding the generalization of the proposed results. This limitation is attenuated by the representativeness of the case study analyzed. Furthermore, the presented work should encourage future analyses as well as expanding the implementation of LSP to other SC 4.0 teaching contexts and applications.

This paper contributes to the very few literatures regarding using gamification in SC education and specifically how LSP methodology can be adopted in teaching SCM 4.0.

The purpose of this paper is to examine the impact of various cultural amenities on tourism demand in 168 European cities.

Using data from the European Commission’s Culture and Creative Cities Monitor 2017, a series of regressions are estimated to examine the impact of various cultural amenities on tourism demand while also controlling for other factors that may impact on tourism demand. Diagnostic tests are also conducted to check the robustness of the results.

The results reveal that cultural amenities in the form of sights, landmarks, museums, concerts and shows have a positive impact on tourism demand. By pinpointing the cultural amenities that are important for increasing tourism demand, the findings aid stakeholders in the tourism industry as they develop post-pandemic recovery plans.

This paper identifies two key aspects of the cultural tourism literature that require deeper investigation and aims to address these aspects. Firstly, while many studies focus on a specific or narrow range of cultural amenities, this study includes a series of measures to capture a range of cultural amenities. Secondly, while many studies are narrow in geographical scope, this paper includes data on 168 European cities across 30 countries.
