This study proposes a novel method utilising a speech-word pair bipartite network to examine the correlation structure between members of parliament (MPs) in the context of the UK- China relationship.

We construct MP-word pair bipartite networks based on the co-occurrence relationship between MPs and words in their speech content. These networks are then mapped into monopartite MPs correlation networks. Additionally, the study calculates correlation network indicators and identifies MP communities and factions to determine the characteristics of MPs and their interrelation in the UK-China relationship. This includes insights into the distribution of key MPs, their correlation structure and the evolution and development trends of MP factions.

Analysis of the parliamentary speeches on China-related affairs in the British Parliament from 2011 to 2020 reveals that the distribution and interrelationship of MPs engaged in UK-China affairs are centralised and discrete, with a few core MPs playing an integral role in the UK-China relationship. Among them, MPs such as Lord Ahmad of Wimbledon, David Cameron, Lord Hunt of Chesterton and Lord Howell of Guildford formed factions with significant differences; however, the continuity of their evolution exhibits unstableness. The core MP factions, such as those led by Lord Ahmad of Wimbledon and David Cameron, have achieved a level of maturity and exert significant influence.

The research has several limitations that warrant acknowledgement. First, we mapped the MP-word pair bipartite network into the MP correlation network for analysis without directly analysing the structure of MPs based on the bipartite network. In future studies, we aim to explore various types of analysis based on the proposed bipartite networks to provide more comprehensive and accurate references for studying UK-China relations. In addition, we seek to incorporate semantic-level analyses, such as sentiment analysis of MPs, into the MP-word -pair bipartite networks for in-depth analysis. Second, the interpretations of MP structures in the UK-China relationship in this study are limited. Consequently, expertise in UK-China relations should be incorporated to enhance the study and provide more practical recommendations.

Firstly, the findings can contribute to an objective understanding of the characteristics and connotations of UK-China relations, thereby informing adjustments of focus accordingly. The identification of the main factions in the UK-China relationship emphasises the imperative for governments to pay greater attention to these MPs’ speeches and social relationships. Secondly, examining the evolution and development of MP factions aids in identifying a country’s diplomatic focus during different periods. This can assist governments in responding promptly to relevant issues and contribute to the formulation of effective foreign policies.

First, this study expands the research methodology of parliamentary debates analysis in previous studies. To the best of our knowledge, we are the first to study the UK-China relationship through the MP-word-pair bipartite network. This outcome inspires future researchers to apply various knowledge networks in the LIS field to elucidate deeper characteristics and connotations of UK-China relations. Second, this study provides a novel perspective for UK-China relationship analysis, which deepens the research object from keywords to MPs. This finding may offer important implications for researchers to further study the role of MPs in the UK-China relationship.

This study proposes a novel scheme for analysing the correlation structure between MPs based on bipartite networks. This approach offers insights into the development and evolving dynamics of MPs.

The emergence of dark kitchens in the restaurant industry is a contemporary phenomenon, arising most recently in the context of the so-called gig economy. This new business model flourished during the coronavirus disease 2019 (COVID-19) pandemic on a global scale. Despite dark kitchens' popularity, considerable negative publicity exists in the news related to poor working conditions. To highlight this new phenomenon, this paper explores the existing literature on worker exploitation in dark kitchens in the context of the gig economy.

A systematic literature review of hospitality and tourism databases generated 1,430 articles, of which 18 met the authors' inclusion criteria for the final analysis, and 1,030 anecdotal sources, of which 47 were included. Thematic analysis was used to identify the key themes and summarise the findings to be used for further studies.

The popularity of dark kitchens as a business model is premised on the fact that dark kitchens' dramatically reduces the operational cost and increases productivity. On the other hand, the working conditions and contractual agreements of the gig workers in dark kitchens raise several questions from operational, legal and ethical perspective. These poor working conditions create the conditions for worker exploitation and further damage the sector's image.

This study advocates that companies and managers are responsible for implementing and monitoring fair working conditions in dark kitchens. The existence of poor working conditions increases employee turnover and, overall, affects the industry's reputation.

This explorative study provides insights into the working conditions and contractual agreements in dark kitchens. Currently, there is no other study (empirical or conceptual) to shed light on the working practices. The authors hope this study will trigger further discussion and empirical research in this field.
