AbstractWith the expansion of 5G networks, new business models are arising where multi-tenancy and active infrastructure sharing will be key enablers for them. With these new opportunities, new security risks are appearing in the form of a complex and evolving threat landscape for 5G networks, being one of the main challenges for the 5G mass rollout. In 5G-enabled scenarios, adversaries can exploit vulnerabilities associated with resource sharing to perform lateral movements targeting other tenant resources, as well as to disturb the 5G services offered or even the infrastructure resources. Moreover, existing security and trust models are not adequate to react to the dynamicity of the 5G infrastructure threats nor to the multi-tenancy security risks. Hence, we propose in this work a new security and trust framework for 5G multi-domain scenarios. To motivate its application, we detail a threat model covering multi-tenant scenarios in an underlying 5G network infrastructure. We also propose different ways to mitigate these threats by increasing the security and trust levels using network security monitoring, threat investigation, and end-to-end trust establishments. The framework is applied in a realistic use case of the H2020 5GZORRO project, which envisions a multi-tenant environment where domain owners share resources at will. The proposed framework forms a secure environment with zero-touch automation capabilities, minimizing human intervention.

Innovation Model

In the article proves that in modern business conditions to ensure a decent competitive position for railway transport companies in the market of transport and logistics services is not possible without active innovation. It is established that recently this type of activity has lost its effectiveness, and therefore does not allow obtaining the desired results. Research has shown that the application of the open innovation model is not yet a guarantee of success for railway transport companies. Studies of existing scientific achievements have led to the conclusion that railway and transport enterprises, despite the restructuring of the railway industry, operate in a single technical and technological chain, and therefore their innovation is dominated by a single innovation and technological cycle using the principles of resource sharing to achieve innovative goals. In view of all the above, as a basis for ensuring the effectiveness of innovation activities of railway transport enterprises should use the sharing of innovation activities. Under such conditions, overall economic efficiency will be determined by a number of local effects: use of agreed transfer prices for works and services between the participants of the cooperation; concentration of financial resources directed to research and development work; testing of production processes and checking the quality and efficiency of new business models; optimization of production volumes for those products for which small and medium scale of production are economically unreasonable; ensuring the stability of the holding structure to bankruptcy situations in market conditions. During research it is established that it is expedient to allocate the basic four models of sharing of innovative resources for the enterprises of railway transport: (sharing of the equipment, sharing of the personnel, sharing of engineering teams, sharing of ideas and developments) accordingly to form mechanisms of their further realization. For railway transport enterprises that are part of cooperative networks and are not linked by cross-capital ownership, the advantages are strategic and operational flexibility, which is also, associated with a higher level of production and information risks.

More people, more organizations, more towns, cities, regions and countries for more reasons have found that over the last 30 years the arts, their broader culture and overall creativity has something in it for them in renewal and revitalization. Over the last decade there have been over a hundred studies of the economic and social importance or impact of the arts, culture, heritage, the recycling of buildings for cultural purposes, creative quarters and the creative economy across the world. Yet there is much more to the arts, culture and creativity in city development. Places in transition urgently need to develop an overall culture of creativity cu ing across all domains within which the arts can be significant. This can be a painful exercise as old certainties crumble and systems, like education, need rethinking. Yet this can unleash new social innovations, new business models and new forms of citizen engagement. Renewal and transformation together are a cultural project involving a shift in mindset and perspective. Creativity is a primary resource as it creates the conditions from which innovations can emerge. Within this the creative economy sectors, especially when aligned to the dramatic digitization dynamic, play a significant role in developing new products and services, generating jobs, anchoring identity and helping expression. Cultural activities and programming and the physical assets of places, their heritage and older industrial buildings are significant elements in the renewal repertoire.

This chapter considers the role played by radio in popularizing and defining country music. Radio as a format pursued a commercially driven mediation of identity that worked against applying an artistically driven musical genre definition. In particular, these debates revolved around gendered presentation and women as listeners and performers. From the 1920s through World War II, radio’s prominence in country turned on live radio shows as the media introduction of southern whites. A second era, from the end of the war to mid-1970s, saw a shift to disc jockeys and records: personality radio. Format radio country, a tighter programming approach, solidified from the mid-1970s to the mega mergers of the late 1990s. Most recently, in an era of Internet access and new business models for music, country has confronted the less sympathetic position of networked radio.

ABSTRACT Firms are often criticized for their reluctance to embrace sustainability in their business strategies. Frugal innovation is a recent concept that represents a new way for firms to serve underserved customers in developing countries while also promoting sustainability. Based on three cases of frugal innovation at the grassroots level in India, this article demonstrates how frugal innovation presents a promising way to tackle some of today's pressing societal problems with new business models. We use a range of parameters for economic, social, and environmental sustainability to strengthen the case for frugal innovation. This article attempts to inspire scholars to consider frugal innovation further in their future research endeavors and encourage firms to integrate it into their existing business models.

Wealth Generation

The global tourism reality is changing, and not only because of the COVID-19 pandemic. This reality is especially representative in countries such as Spain, which are highly dependent on the income generated by the tourism sector. In these destinations, it is necessary to seek innovation and specialization in the sector in order to achieve new business models. This need is even more pressing in destinations overcrowded by the sun and beach effect, as is the case of Mallorca. The proposed work combines the concepts of sports tourism with the development of a wealth-generating business model that will contribute to promoting a tourism that is sustainable, environmentally friendly and deseasonalized. On the other hand, the proposed work will contribute to promoting integration and equality in the participation of women in sports through the development of a model based on the promotion of women’s football. Using the methodology of case analysis, the results of all the approaches outlined are provided, and we obtained a wealth-generation model that is easily replicable and sustainable over time. This work provides a solution to the combination of a sustainable business model that links responsible tourism, the promotion of women’s sport and the generation of wealth.
