The trade-off and synergy relationship between ecosystem services (ESs) and human well-being (HWb) in the land-use process has become a research hotspot. The evolutionary process and regional contribution of the accurate quantification of ESs and HWb can provide a reference for government departments to formulate macroeconomic policies. Therefore, this study first constructed an analysis framework to identify the synergistic states/evolutionary stages of the gross ecosystem product (GEP) per capita (PGEP) and gross domestic product (GDP) per capita (PGDP) and the regional contribution of the GEP–GDP synergy of 362 municipal units in mainland China from 2000 to 2015. We did this by employing the Markov transition probability matrix, land use data, and economic data based on satellite remote sensing images. The findings of this study show that (1) the PGEP of the Chinese mainland has a remarkable spatial divergence featuring a higher value in the northwestern Chinese mainland and a lower value in the southeastern Chinese mainland on both sides of the Hu Line during the investigation period; despite the eastern Chinese mainland having a higher PGDP, the PGDP at the national level is distributed in dispersion on both sides of the Hu Line; (2) during the first half of the investigation period, the GEP–GDP synergy in the Chinese mainland was generally in the pseudo-synergy stage or the transition stage from pseudo-synergy to primary/intermediate synergy, while in the second half of the period, the GEP–GDP synergy in the Chinese mainland continued to improve; (3) the GEP–GDP synergy was relatively stable on the Chinese mainland during the investigation period, with 24.28% of the units shifting to a lower or higher level synergy, and the GEP–GDP synergy was more stable in the western and central Chinese mainland, while it was more likely to shift to a higher state in the northeastern and eastern Chinese mainland. This study suggests that the GEP–GDP relationship varies with spatial scales; a hierarchical, multiscale ...

To guarantee information security in communication, quantum identity authentication plays a key role in politics, economy, finance, daily life and other fields. In this paper, a new quantum multiparty simultaneous identity authentication protocol with Greenberger–Home–Zeilinger (GHZ) state is presented. In this protocol, the authenticator and the certified parties are the participants with quantum ability, whereas the third party is a classical participant. Here, the third-party is honest and the other two parties may be dishonest. With the help of a classical third-party, a quantum authenticator and the multiple certified parties can implement two-way identity authentication at the same time. It reduces the quantum burden of participants and lowers down the trustworthiness, which makes the protocol be feasible in practice. Through further security analysis, the protocol can effectively prevent an illegal dishonest participant from obtaining a legitimate identity. It shows that the protocol is against impersonation attack, intercept-measure-resend attack and entangle-measure attack, etc. In all, the paper provides positive efforts for the subsequent security identity authentication in quantum network.

PurposeFrancois Quesnay, known as the "Confucius of Europe", was profoundly influenced by traditional Chinese culture to form his thoughts, which contained strong Chinese characteristics. This paper aims to examine economic thought of Francois Quesnay from the perspective of the construction of socialist political economics with Chinese characteristics.Design/methodology/approachMoreover, his thoughts also profoundly influenced subsequent economists, such as Adam Smith and Karl Marx. It can be said that Francois Quesnay was at the intersection of Chinese, Western and Marxist thought systems, so it is quite important to examine his thoughts critically and conduct source-tracing in China.FindingsHence, in the process of constructing and developing socialist political economy with Chinese characteristics, there is an urgent need to focus on exploring the value of excellent traditional Chinese culture at the theoretical level and combining the development and dissemination of the history of thoughts and the historical position of Chinese reality to realize the innovation and development of socialist political economy with Chinese characteristics.Originality/valueMeanwhile, while absorbing nutrition from excellent traditional Chinese culture, it is necessary to establish scientific coordinates rather than use the discourse systems and paradigms of Western economics to interpret ancient Chinese economic thoughts. It is necessary to adhere to, inherit and develop Marxist political economy and absorb nutrition from Chinese excellent traditional culture to construct socialist political economy with Chinese characteristics.

This study analyzed news stories published on the online sites of CNN, Al-Jazeera English, and Sputnik to investigate how the transnational news outlets framed the human suffering associated with the Syrian war. Unlike prior studies that have tended to be based on traditional nation-state paradigms, this research approached the analysis from a cosmopolitan perspective. The findings revealed that in concert with standard journalistic routines and news values, all three news outlets commonly employed a mass death and displacement frame to depict human suffering inside Syria. The adoption of this frame suggests that in telling the story of human suffering, the three media outlets focused on brief facts and shocking statistics without detailed depictions of the human suffering. The meager presence of a cosmopolitan outlook in the news coverage indicates that although transnational media target a global audience with English as Lingua Franca, they cannot be completely independent of geopolitics.

This study examines elements of what has been defined as global journalism and compares online news stories of Al Jazeera English and CNN regarding the ISIS threat. The empirical inquiry presents the similarities and differences in transnational news outlets' coverage of a global crisis. The results of a quantitative content analysis (N = 320) suggest that different transnational news outlets share some features in their news coverage of a global challenge but still differ significantly. CNN mostly cites governmental official sources, whereas Al Jazeera English relies more on information from other news media. In addition, CNN mainly adopts a geopolitics frame focusing on the strategies of dealing with ISIS, whereas Al Jazeera English uses the dominant frame of existential threat. Results further indicate that elements of global journalism do not go beyond human rights issues.

Purpose of this paper: Alternatively fuelled vehicles (AFVs) have received increasing attention from policy makers and industry practitioners because they are perceived as a silver bullet for decarbonising freight transport (Mohammed et al., 2020; ITF 2021). However, the uptake rate of AFVs by heavy goods vehicle (HGV) freight operators in Europe remains low. With 97.8% of all trucks in the EU running on diesel, only 0.04% of trucks are zero-emission vehicles (ACEA, 2021). Price, technology maturity, infrastructure, and government policy support are factors examined by freight transport operators who consider the switch to AFVs as a low-carbon option (Mohammed et al., 2020). Research studies have identified enablers and barriers for adopting AFVs. Practical guidance and tools for decision making from freight transport operators' perspectives are still limited. This ongoing research study assesses the maturity of AF (Alternatively Fuelled) HGVs by exploring the experiences of innovators and early adopters of AF HGVs in Ireland. To achieve this aim, two research questions are answered: How mature is the adoption of AF HGVs, and what are the experiences of innovators and early adopters of AF HGVs in Ireland? Design/methodology/approach: Initially, a framework of determinants for deciding on the adoption of AF HGVs was developed from a review of recent literature. Furthermore, to assess the maturity of AF HGVs uptake by freight transport operators a maturity framework is proposed based on the technology adoption lifecycle and the capability maturity model. Qualitative data collection methods have been employed to interview innovators and early adopter operators of AF HGVs in Ireland. The developed frameworks informed the development of the interview guide and were used as a template of a-priori codes for the analysis of the empirical data. Findings: A conceptual maturity assessment framework, which is based on the technology adoption lifecycle, is proposed to enable HGV freight operators to assess their readiness ...
