5G systems will enable an improved transmission performance and the delivery of advanced communication services. To meet the expected requirements, operators will need to invest in network modernisation, with the radio access network being the most expensive network component. One possible way for operators to reduce this investment would be via sharing of resources by means of a multi-tenancy concept. This implies that a mobile service provider may use the common infrastructure of one or various infrastructure providers, whereby it provides services to multiple tenants. This paper aims to study the expected cost savings in terms of capital expenditures (CAPEX) and operational expenditures (OPEX) that can be achieved when using a cloudified 5G multi-tenant network.

A cost model was used. The study period is 2020-2030 and the study area consists of three local districts in central London, UK.

This paper describes that the total cost reduction achieved when using multi-tenancy for a 5G broadband network in comparison with the case where operators make the investment independently ranges from 5.2% to 15.5%.

Further research is needed to assess the cost implications of network sharing for 5G on a regional or nationwide basis.

Very little quantitative research about the cost implications of network sharing under 5G networks has been published so far. This paper sheds light on the economic benefits of multi-tenancy in a 5G broadband network.

Urbanisation is trending globally, leading to population densification and housing shortage and people living increasingly in isolation. This entails challenges to sustainable development including ecological, social and well-being issues. This paper aims to evaluate the effects of a six-month onboarding self-leadership programme including exercises in mindfulness and acceptance and commitment therapy, amongst residents in a co-living space (n = 24) and a waiting list (n = 21).

At baseline and post-intervention, participants filled out questionnaires and two waves of in-depth interviews (n = 24) were conducted. Repeated measures one-way analysis of variance and thematic text analyses were performed.

Participation in the programme significantly (all ps < 0.000 to 0.050) improved relationship quality and communication about one’s needs regarding work-non-work boundaries, especially amongst residents at the co-living space. Moreover, programme participation significantly increased perceived work-non-work boundary control, work-life balance, psychological well-being, psychological flexibility and self-compassion, with effect sizes (hp2) in the medium to the large range (0.14 to 0.39). Qualitative findings suggested that increased psychological flexibility and self-compassion encouraged co-living residents to be more vulnerable and trusting, which enabled communication regarding one’s needs and enhanced mutual social support and relationship quality. This, in turn, improved overall boundary management, work-life balance and well-being.

Co-living settings – while contributing to overall sustainable development through more efficient use of space and resources – can also contribute to societal and individual sustainability. However, to ensure this contribution, the physical environment including private areas and common and semi-public areas, as well as the socio-emotional environment need to be considered.

This article develops conceptual and paradigmatic clarity in the circular economy literature from a management studies perspective.

This article uses a systematic literature review for analysing how circular economy is currently understood. It also reflects on how to establish paradigmatic anchoring of the circular economy in the management field.

Multiple definitions of the circular economy exist, but they depict the circular economy narrowly and fail to incorporate aspects of competitiveness and profitability. Additionally, most of sustainability management research displays shortcomings in the way this literature frames the organisation–nature relationship.

This article aims to support conceptual and theoretical development in the circular economy literature and highlights opportunities for enhanced competitiveness and profitability deriving from circular business model innovation. However, further research is welcomed to assess this connection.

The conceptualisation of the circular economy proposed in this study emphasises aspects of competitiveness and profitability, which is of relevance to management practitioners.

This study addresses current shortcomings in how the circular economy is conceptualised. As a result, it proposes a more comprehensive conceptualisation which also includes competitiveness and profitability aspects and, thereby, is relevant from a management studies perspective. It also provides paradigmatic anchoring to the circular economy concept by suggesting that the sustaincentric paradigm, which has received limited scholarly attention so far, is suitable to inform circular economy research and practice.
