Abstract
The COVID-19 pandemic has disrupted the ‘real’ world and substantially impacted the virtual world and thus the Internet ecosystem. It has caused a significant exogenous shock that offers a wealth of natural experiments and produced new data about broadband, clouds, and the Internet in times of crisis. In this chapter, we characterise and evaluate the evolving impact of the global COVID-19 crisis on traffic patterns and loads and the impact of those on Internet performance from multiple perspectives. While we place a particular focus on deriving insights into how we can better respond to crises and better plan for the post-COVID-19 ‘new normal’, we analyse the impact on and the responses by different actors of the Internet ecosystem across different jurisdictions. With a focus on the USA and Europe, we examine the responses of both public and private actors, with the latter including content and cloud providers, content delivery networks, and Internet service providers (ISPs). This chapter makes two contributions: first, we derive lessons learned for a future post-COVID-19 world to inform non-networking spheres and policy-making; second, the insights gained assist the networking community in better planning for the future.

Abstract
Purpose
Fewer researchers have investigated the climatic and economic drivers of land-use change simultaneously and the interplay between drivers. This paper aims to investigate the nonlinear and interaction effects of price and climate variables on the rice acreage in high-latitude regions of China.
Design/methodology/approach
This study applies a multivariate adaptive regression spline to characterize the effects of price and climate expectations on rice acreage in high-latitude regions of China from 1992 to 2017. Then, yield expectation is added into the model to investigate the mechanism of climate effects on rice area allocation.
Findings
The results of importance assessment suggest that rice price, climate and total agricultural area play an important role in rice area allocation, and the importance of temperature is always higher than that of precipitation, especially for minimum temperature. Based on the estimated hinge functions and coefficients, it is found that total agricultural area has strong nonlinear and interaction effects with climate and price as forms of third-order interaction. However, the order of interaction terms reduces to second order after absorbing the expected yield. Additionally, the marginal effects of driven factors are calculated at different quantiles. The total area shows a positive and increasing marginal effect with the increase of total area. But the positive impact of price on the rice area can only be observed when price reached 50% or higher quantiles. Climate variables also show strong nonlinear marginal effects, and most climatic effects would disappear or be weakened once absorbing the expected rice yield. Expected yield is an efficient mechanism to explain the correlation between crop area and climate variables, but the impact of minimum temperature cannot be completely modeled by the yield expectation.
Originality/value
To the best of the authors’ knowledge, this is the first study to examine the nonlinear response of land-use change to climate and economic in high-latitude regions of China using the machine learning method.

Abstract
Purpose
Sex tourism is well documented in the literature, but what about porn tourism? Whether it is a Ping Pong show in Phuket or the Banana show in Amsterdam, porn and tourism have an encounter and gaze no different from the Mona Lisa in the Louvre or magnificent views of New Zealand’s Southern Alps. The paper aims to discuss these issues.
Design/methodology/approach
This paper explores the intersections of tourism, porn and the future as a conceptual framework.
Findings
Four intersections are derived from the conceptual framework. Intersection 1, the Future of Tourism, portrays the evolution of tourism and explores its technological future. Interaction 2, Porn in Tourism, distinguishes between soft- and hard-core porn tourism. Intersection 3, Portraying Porn as a Future Dimension, delves into futurism, science fiction and fantasy. The fourth intersection, the Future Gaze, conveys the thrust of the paper by exploring how technological advancement blends with authenticity and reality. Thus the porn tourist seeks both the visual and the visceral pleasures of desire. The paper concludes with four future gazes of porn tourism, The Allure of Porn, The Porn Bubble, Porn as Liminal Experience and Hardcore.
Originality/value
The originality of this paper is that this is the first paper to systematically examine porn tourism beyond sex tourism overlaying with a futures dimension. Porn tourists actively seek to experience both visual and visceral pleasures. Tourism and pornography both begin with the gaze. The gaze is an integral component of futures thinking. Technology is changing us, making us smarter, driving our thirst for liminal experiences. Like the transition from silent movies to talking pictures the porn tourism experience of the future is likely to involve more of the bodily senses.

Abstract
Purpose
This paper aims to interpret the multidimensional Asian American identity of immigrant Indians in terms of pan-ethnicity, gender and religion.
Design/methodology/approach
The social construction and experience of race in the US and the intersection of multiethnic Asian American identity with race, gender and religion will be used in critically commenting on the interview of primary ethnic identity of Indian Americans including the pan-ethnic identity of Indians in the US as Asian Americans, the Mar Thoma Church community, the second-generation Patel family's union formation in terms of gender identity.
Findings
The future directives include Asian American Movement (AAM) which is trying to incorporate Indians as pan-ethnic identity assimilation and the process of holding American identity as primary identification of Indians.
Practical implications
Policy recommendations are that the US Census Bureau should include Indian Americans as separate ethnic identity for Indian immigrants like the Chinese Americans. USCIS (US Citizenship and Immigration Services) should reform policies to include the wives of H-4 visa holders. The Department of Homeland Security (DHS) should provide secure living environment for Indian immigrants. The US Department of Labor should provide equal opportunities for women in their immigration policies.
Originality/value
This paper will critically analyze the interview results of primary ethnic identity and justify the hypotheses of Asian American identity of Indians, whether (1) they merge with the American identity as part of cultural assimilation or (2) retain their Asian identity beyond Americanized identity or (3) go beyond both American and Asian identity to restate their Indian ethnicity.

Abstract
Purpose
The porpose of this study is to critically consider the use of global reporting initiative (GRI) guidelines in universities’ sustainability reports.. In light of the recent literature and Habermas’s thinking, the study advances the research field by considering the process of internal colonisation from steering institutions and makes suggestions regarding the future role of GRI in the higher education (HE) context.
Design/methodology/approach
This study presents a systematic literature review and content analysis for enhancing the critical reading of GRI applications in HE studies. The results are analysed in light of Habermas’s thinking, considering the GRI as a steering institution and its guidelines as steering mechanisms.
Findings
This study updates the literature review on sustainability reporting (SR) at universities and underlines the general trend in the employment of the GRI in this context. The results highlight the need to adapt the GRI to enhance its applicability in the HE context by considering additional dimensions such as research, teaching and operations. In doing so, the framework loses effectiveness and weakens the role of the GRI as a steering institution.
Practical implications
The results suggest that the GRI guidelines should be reframed to enhance comparability among reports and increase its wider employment at universities.
Social implications
Universities need to be guided in their accountability process towards SR by dedicated frameworks. This study suggests the potentially pivotal role that the GRI could play in providing dedicated tools for HE to steer and enhance the development of SRs at universities.
Originality/value
This study presents an updated review of studies on SR at universities and suggests possible paths for the future of the GRI framework applicability to universities’ SR.

Abstract
Purpose
Higher education institutions (HEIs) have a great responsibility to put education for sustainable development at the centre of their work. Curricula should therefore start to incorporate the sustainable development goals (SDGs) and key competencies in sustainability, and research should be carried out to determine effective learning methods for this. This study aims to explore the usefulness of problem-based learning (PBL) approaches to train biomedical students in sustainability and to provide some recommendations for the design and implementation of new PBL-SDG scenarios.
Design/methodology/approach
Two PBL-SDG scenarios were designed, implemented and evaluated for 110 students of human biology degree. Learning outcomes and student perceptions of this approach were analysed through questionnaires, student productions, non-participant observation and focus groups.
Findings
The results show that the PBL-SDG scenarios effectively addressed several SDGs and sustainability competencies in a transversal, collaborative and innovative manner. According to student perceptions, the elements that contributed most to the development of these competencies were emotional involvement with the scenario, reflection on their own actions, freedom to approach the problem and tutors who empowered them with their proposals.
Originality/value
The PBL-SDG approach presented in this study is an example of a pedagogical strategy that can help HEIs educate their learners as key change agents. The findings of this study provide evidence for this important aspect and give guidelines and strategies to successfully designing and implementing such methodologies in biomedical education.

Abstract
Purpose
The purpose of this paper is to examine bank performance using the different performance measures, namely, return on assets, return on equity and bank margins (MAR).
Design/methodology/approach
Unbalanced panel data were constructed to test the related hypotheses and provide evidence on the relationship between ownership types, banking models and performance indicators adopting the random effects techniques.
Findings
The findings of the paper substantiate that the banking models are significant performance indicators. However, the results are contingent on the GDP growth of the country. Moreover, the evidence indicates that the impact of ownership types is inconclusive in all measures of performance. However, the GDP is significant when it interacts with the types of ownership, particularly for foreign and government banks, although the evidence is mixed and unfavourable for government banks.
Practical implications
The results of the study provide insights for bankers and policymakers to enhancement Yemen’s banking sector.
Originality/value
This study is considered as the first attempt in examining the role of banking model and ownership type and their link to banking model.

Abstract
Purpose
This paper aims to describe the development of a knowledge management system (KMS) for the Nadir and Occultation for Mars Discovery (NOMAD) instrument on board the ESA/Roscosmos 2016 ExoMars Trace Gas Orbiter (TGO) spacecraft. The KMS collects knowledge acquired during the engineering process that involved over 30 project partners. In addition to the documentation and technical data (explicit knowledge), a dedicated effort was made to collect the gained experience (tacit knowledge) that is crucial for the operational phase of the TGO mission and also for future projects. The system is now in service and provides valuable information for the scientists and engineers working with NOMAD.
Design/methodology/approach
The NOMAD KMS was built around six areas: official documentation, technical specifications and test results, lessons learned, management data (proposals, deliverables, progress reports and minutes of meetings), picture files and movie files. Today, the KMS contains 110 GB of data spread over 11,000 documents and more than 13,000 media files. A computer-aided design (CAD) library contains a model of the full instrument as well as exported sub-parts in different formats. A context search engine for both documents and media files was implemented.
Findings
The conceived KMS design is basic, flexible and very robust. It can be adapted to future projects of a similar size.
Practical implications
The paper provides practical guidelines on how to retain the knowledge from a larger aerospace project. The KMS tool presented here works offline, requires no maintenance and conforms to data protection standards.
Originality/value
This paper shows how knowledge management requirements for space missions can be fulfilled. The paper demonstrates how to transform the large collection of project data into a useful tool and how to address usability aspects.

Abstract
Purpose
The purpose of this study is to focus on the informal learning (IL) processes of teachers in primary and secondary schools in Spain. Its objective is to study the strategies currently used by teachers to generate IL, identifying the factors that condition such learning and the changes that must be introduced to enhance it.
Design/methodology/approach
The methodology is qualitative, with information from interviews with school principals (n = 21) and teachers (n = 60) from 22 primary and secondary schools in Spain and from 3 discussion groups with experts (n = 17). The topics used refer to strategies to generate and promote IL and its conditioning factors.
Findings
The findings suggest that, regardless of the stage (primary/secondary) and ownership of the centre (state/private), the teaching staff use IL strategies that, beyond individual actions, involve meeting, sharing and reflecting with other teachers. The challenge is that IL facilitates both professional development and the development and improvement of the organizations. School principals play a central role in achieving this relationship and promoting the institutionalization of changes and educational administration in facilitating the right conditions for their development and recognition.
Research limitations/implications
Given that the participation of schools in the research was voluntary, as was that of the teachers who agreed to be interviewed, some bias may exist. To refine the analyses it would also have been interesting to contrast with the people interviewed some of the assessments which appeared in the focus groups. Finally, future work might focus on analysing in greater detail the effect of different management styles on IL.
Practical implications
The results presented point to the need for decisive support from school leadership teams for collaborative work processes and joint reflection, which are one of the basic conditions for facilitating IL and, at the same time, for encouraging organizational learning. Furthermore, in the Spanish context, there is the challenge of combining the participation of teachers in formal training actions with the recognition of IL generated in the development of daily professional activity.
Originality/value
The data provided complements and reaffirms the findings of research carried out in other types of organizations, at the same time highlighting the importance of horizontal relationships among education professionals and the difficulty of creating a solid foundation for organizational changes. Improvements are, on the other hand, highly conditioned by the role adopted by school principals.
