The digital economy has become a key force supporting the high-quality development of tourism. This paper discusses the coupling coordination relationship and spatiotemporal evolution path of digital economy and tourism in China's provinces.

This paper uses the entropy method to measure the development level of digital economy and tourism, and establishes coupling coordination model and spatial autocorrelation model to study the interaction between the two industries.

Results show that the development levels of the two industries are rising, which spatially show a progressively decreasing pattern of east-middle-northeast-west. The coupling coordination degrees of the two industries have increased steadily, but the overall level is still near maladjusted. Spatially, the positive correlation is increasing, but the incongruity of spatial agglomeration is still significant. The coupling coordination evolution path in the provinces shows differentiated characteristics. The migration path is mainly concentrated in Zones I and II. The eastern region has an obvious trend of extending to Zone III, where the tourism industry was the most affected by the pandemic.

The study helps clarify the industrial coupling and coordination relationship in various regions and formulate regional tourism digital transformation strategies to promote the high-quality development of China's tourism industry.

This paper enriches the research on the relationship between digital economy and tourism from the perspective of industrial integration. The development commonality of China's tourism digital transformation summarized provides theoretical reference and demonstration for the coordinated development of China's tourism.

Immigrant integration through entrepreneurship is hindered by the prevalent informality of their ventures. This study aims to examine the factors influencing the formalisation of immigrant entrepreneurship, with special focus on those who are under the impact of the host country.

The study is based on a series of focus groups conducted among a total of 59 Ukrainian immigrants in Poland. Based on coding into first-order categories, second-order themes and aggregate dimensions, the authors created a model of immigrant entrepreneurship formalisation.

The results of the research included in the model show the groups of factors influencing the formalisation of immigrant entrepreneurship. Immigrants bring both their personal attitudes and embeddedness in their country of origin during immigration. Then, factors of the host country’s institutions, interactions between local authorities and local communities and the need for a new place of belonging interact in the formalisation process. Formal entrepreneurs, as a new identity for immigrants, are the result of the formalisation process.

The results not only focus on social capital or the institutional failures of formal and informal institutions in transforming immigrants into formal entrepreneurs, but we also recognise the individual aspect of the new identity as formal entrepreneurs and a new place of belonging. In addition, the authors distinguish the importance and interactions between local communities and local authorities in this process. The paper contributes to the theory of entrepreneurship, migrant study and institutional theory.

In recent years, using aberration-corrected transmission electron microscopy, the authors have achieved precisely detecting the structural evolution of passive film as well as its interface zone at atomic scale. The purpose of this paper aims to make a brief review to show the authors’ new understanding and perspective on the issue of critical factors determining stability of passive film of Fe-Cr alloy.

The introduction of single crystal enabled the authors to obtain a distinct metal/passive film interface and better characterize the structure of the interface region. The authors use aberration-corrected TEM to conduct cross-sectional observation and directly capture the details across the entire film at a high spatial and energy resolution.

Apart from the passive film itself, the interface zone, including metal/film (Me/F) interface and the adjacent metal side, is also the site which is attacked. Accordingly, the nature of the interface zone, such as microstructure, composition and atomic configuration, is one of the critical factors determining the stability of passive film.

Deciphering the critical factors determining the stability of passive film is of great significance and has been a fundamental issue in corrosion science. Great attention has been paid to the nature of the passive film itself. In contrast, the possible role of the interface between the passive film and the metal is rarely taken into account. Based on the advanced analytical tool with high spatial resolution, the authors have specified the significant role of interface structures on the macro-scale stability of passive film.

The paper covers mega infrastructure construction supply chain (MICSC) in Engineering-Procurement-Construction (EPC) projects, where the frequent occurrence of risk incidents has greatly affected human life. The research aims to establish a risk evaluation index system for MICSC in EPC projects, exploring what risk factors lead to risk incidents and measure the importance and causality of all these risk factors.

The research applies a combination of quantitative and qualitative analysis methodology to process data sequentially. In the first place, risk factors for MICSC in EPC projects are extracted and identified from literature survey and expert interviews. In the second place, an integration model fuzzy Analytic Hierarchy Process (f-AHP) and fuzzy Decision-making Trial and Evaluation Laboratory (f-DEMATEL) is constructed to comprehensively analyze all these risk factors.

12 primary risk factors and 36 secondary risk factors comprise the risk evaluation index system for MICSC in EPC projects from 178 literature and 5 professionals. The results indicate that Political Situation (F1), Social Security (F2) and Management Mode (F8) are critical risk factors, where F1 and F2 are cause factors and F8 is an effect factor.

There are three main contributions of this paper. First and foremost, from the perspective of the research content, no other study has been able to assess risk factors for MICSC in EPC projects, while embedding nine phases of the whole project life cycle and six subjects of stakeholders into a risk evaluation index system. Additionally, from the perspective of research method, a combined model incorporating f-AHP and f-DEMATEL is constructed to avoid the one-sidedness of a single model. Last but not least, from the perspective of practical significance, focusing on the critical risk factors, a series of effective measures are formulated to make appropriate management decisions for nodal enterprises of MICSC, which can improve their risk management capabilities.

Skilled migrant (SM) women play a key role in developed countries especially in healthcare and education in easing staffing shortages and migrate expecting to gain qualification-matched employment (QME). The aim of this review is to assess whether SM women gain the anticipated QME, equitably compared to their skilled counterparts and to examine why and how they do so.

I conducted a systematic literature review to derive empirical studies to assess if, why and how SM women achieve QME (1) using SM women-only samples and comparative samples including SM women, and (2) examining whether they gain QME directly on or soon after migration or indirectly over time through undertaking alternative, contingent paths.

Only a minority of SM women achieve the anticipated QME directly soon after migration and less often than their skilled counterparts. Explaining the mechanism for achieving QME, other women, especially due to having young families, indirectly undertake alternative, lower-level contingent paths enabling them to ascend later to QME.

The SM literature gains new knowledge from revealing how SM women can gain positions post-migration comparable to their pre-migration qualifications through undertaking the alternative, contingent paths of steppingstone jobs and academic study, especially as part of agreed familial strategies. This review results in a theoretical mechanism (mediation by a developmental contingency path) to provide an alternative mechanism by which SM women achieve QME.

Through the reconstruction of the events of some foreign entrepreneurs who worked in the territory of the Italian city of Bari in the first half of the 19th century, this paper aims to analyze the role of entrepreneurial migration in the economic development of Apulia land in this period.

This study adopts a theoretical framework that combines the concept of mixed embeddedness in a multifocal perspective, with the model of the diffusion of innovation focusing on the role of the so-called agency of actors, and of the network, in the dissemination of innovation. The theoretical framework is applied to multiple case studies to compare the evidence that emerged from the simultaneous analysis of several situations.

By analyzing how innovations have spread within the network of entrepreneurs of that time, it is possible to identify some relevant aspects related to the mechanisms of dissemination of innovations in the context of entrepreneurial migration. Specifically, the opportunity structure is intended in an even broader sense than indicated in the classic approach to mixed embeddedness: it is considered as the result of the joint interaction of the political, institutional and economic context of several places, and the behavioral dynamics of several groups.

Due to the specific method chosen, the outcomes of the research might apply to a narrow context. Therefore, the results need to be tested and confirmed in further empirical studies, and by applying multiple research methods.

Findings are useful and significant in the analysis of the link that exists between the diffusion of innovations and migrant entrepreneurship, and then the conclusions can be applied and extended to the current phenomenon of migration-related innovations, with specific reference to developing countries.

Findings can be applied and extended to the current phenomenon of migration-related innovations and highly skilled migration, with specific reference to developing countries.

This paper contributes to shed new light on the contextual and multifocal factors that influence the development of innovations in the networks of migrant entrepreneurship, in a specific historical period and a specific context. Combining social, human and financial capital with the wider opportunity structure, this study also provides a comprehensive understanding of the modalities through which migrant and high-skilled entrepreneurs could innovate.

A cross-domain intelligent software-defined network (SDN) routing method based on a proposed multiagent deep reinforcement learning (MDRL) method is developed.

First, the network is divided into multiple subdomains managed by multiple local controllers, and the state information of each subdomain is flexibly obtained by the designed SDN multithreaded network measurement mechanism. Then, a cooperative communication module is designed to realize message transmission and message synchronization between the root and local controllers, and socket technology is used to ensure the reliability and stability of message transmission between multiple controllers to acquire global network state information in real time. Finally, after the optimal intradomain and interdomain routing paths are adaptively generated by the agents in the root and local controllers, a network traffic state prediction mechanism is designed to improve awareness of the cross-domain intelligent routing method and enable the generation of the optimal routing paths in the global network in real time.

Experimental results show that the proposed cross-domain intelligent routing method can significantly improve the network throughput and reduce the network delay and packet loss rate compared to those of the Dijkstra and open shortest path first (OSPF) routing methods.

Message transmission and message synchronization for multicontroller interdomain routing in SDN have long adaptation times and slow convergence speeds, coupled with the shortcomings of traditional interdomain routing methods, such as cumbersome configuration and inflexible acquisition of network state information. These drawbacks make it difficult to obtain global state information about the network, and the optimal routing decision cannot be made in real time, affecting network performance. This paper proposes a cross-domain intelligent SDN routing method based on a proposed MDRL method. First, the network is divided into multiple subdomains managed by multiple local controllers, and the state information of each subdomain is flexibly obtained by the designed SDN multithreaded network measurement mechanism. Then, a cooperative communication module is designed to realize message transmission and message synchronization between root and local controllers, and socket technology is used to ensure the reliability and stability of message transmission between multiple controllers to realize the real-time acquisition of global network state information. Finally, after the optimal intradomain and interdomain routing paths are adaptively generated by the agents in the root and local controllers, a prediction mechanism for the network traffic state is designed to improve awareness of the cross-domain intelligent routing method and enable the generation of the optimal routing paths in the global network in real time. Experimental results show that the proposed cross-domain intelligent routing method can significantly improve the network throughput and reduce the network delay and packet loss rate compared to those of the Dijkstra and OSPF routing methods.

The worldwide interdependency of nations has been acknowledged throughout the globalization literature and by many national and international organizations, including higher education institutions (HEIs), which have become an essential tool to accelerate this process. Financial, cultural, and political motives have driven 21st century higher education (HE) toward a more international direction shaping HE policies and promoting the mobility of ideas and individuals across the world. Utilizing bibliometric and descriptive tools, the article aims to analyze the existing knowledge base on international mobility of academics (IMA) as a core component of internationalization. More specifically, the study examines 423 papers published between 1970 and 2021 in Scopus and Web of Science (WoS) databases to reveal the big picture of the knowledge base by identifying the volume, growth trajectory, geographical dispersion, the most influential authors, articles, journals as well as the intellectual structure and the topical foci in the field. The findings have produced four distinct schools of thought labeled as “Knowledge Transfer and Mobility Networks,” “Academic Mobility in IHE Process,” “Expatriate Studies,” and “Scientific Mobility.” Moreover, the co-occurrence keyword map has yielded several topical foci: “Internationalization and Expatriate Academics,” “Academic Mobility and Career Paths,” and “Knowledge Transfer, Migration, and Academic Identity.” Considering the general trends and developments in the field, the study might provide more insight into further research.

In this paper, the authors suggest that Central Americans can use entrepreneurship to solve economic uncertainty in their home country and that entrepreneurship can contribute to reducing the number of undocumented migrants to the USA.

The authors first illustrate the context of Central American illegal migration to the USA from a transitional entrepreneurship perspective, the authors address the economic drivers of illegal migration from Central America, which results in marginalization in the USA. Second, the authors build a theoretical model that suggests that Central Americans can improve their entrepreneurial abilities through the entrepreneurial cognitive adjustment mechanism.

Central Americans at risk of illegally migrating to the USA have high entrepreneurial aptitudes. Entrepreneurship can help them avoid the economic uncertainty that drives Central Americans to illegally migrate to the USA and become part of a marginalized community of undocumented immigrants. This conceptual paper introduces an entrepreneurial cognitive adjustment mechanism as a tool for Central Americans to reshape their personalities and increase their entrepreneurial abilities in their home countries. In particular, entrepreneurial intentions reshape the personality characteristics of individuals (in terms of high agreeableness and openness to experiences, as well as low neuroticism) through the entrepreneurial cognitive adjustment mechanism, which consists of reflective action in sensemaking, cognitive frameworks in pattern recognition and coping in positive affect.

This paper studies Central Americans at risk of illegal migration using the lens of transitional entrepreneurship, which advances the understanding of the antecedents to marginalized immigrant communities in the USA and suggests a possible solution for this phenomenon. Besides, the authors build a cognitive mechanism to facilitate the transitional process starting from entrepreneurial intention to reshaping individuals' personality, which further opens individuals' minds to entrepreneurial opportunities. Since entrepreneurial intention applies the same way to all entrepreneurs, the authors' aim of constructing the entrepreneurial intention unfolding process will go beyond transitional entrepreneurship and contribute to intention-action knowledge generation (Donaldson et al., 2021). Moreover, the conceptual study contributes to public policy such that international and local agencies can better utilize resources and implement long-term solutions to the drivers of illegal migration from Central America to the USA.

This chapter examines changes in Nigerian family roles because of the gap that exists in communication between left-at-home footballers' wives and their absentee husbands who are working at significant distances from their families' permanent residence. Based on a study of 12 football (i.e., soccer) players in the Nigeria Professional Football League (NPFL) and contextualized within the field of sport labor, the study adds knowledge about the impact of footballer migration on left-behind families. The interview data produced five major themes: long-distance marital communication, effects of a paternalistic family culture, extended family issues, effects of father's absence on children, and effects of loneliness and loss of intimacy on wives. The results demonstrate changing roles among the married couples and extended families who were investigated in this study, perhaps indicating what is happening among similar families in Nigeria. It is notable that although the demands of professional football create this impact on families, there is considerable cultural resistance to role changes, because these changes grant the women new and possibly unexpected roles and increased domestic power. Their husbands, despite being away from home, appear to resist these changes and struggle to assert traditional power from afar. In many cases, the women expertly maneuver around this struggle and, in cases where disagreements emerge, they often use effective strategies to resolve problems and maintain a united family.
