This work explored the mediating effects of affective commitment on transformational leadership and job performance and job insecurity on transformational leadership and affective commitment. Meanwhile, the inter-relationships between the four verified the mediating effect of affective commitment, including job insecurity. The results were as follows: transformational leadership and job performance were positively related. Transformational leadership was proportional to an emotional commitment. The affective commitment had a positive impact on job performance. Transformational leadership indirectly positively affected job performance through the intermediary (...) effect of affective commitment. Transformational leadership regulated affective commitment through job insecurity. The more job security employees have, the higher the impact of transformational leadership on affective commitment; the lower the contrary. (shrink)

This study explored the global cyberspace security issues, with the purpose of breaking the stereotype of people’s cognition of cyberspace problems, which reflects the relationship between interdependence and association. Based on the Apriori algorithm in association rules, a total of 181 strong rules were mined from 40 target websites and 56,096 web pages were associated with global cyberspace security. Moreover, this study analyzed support, confidence, promotion, leverage, and reliability to achieve comprehensive coverage of data. A total of 15,661 sites mentioned (...) cyberspace security-related words from the total sample of 22,493 professional websites, accounting for 69.6%, while only 735 sites mentioned cyberspace security-related words from the total sample of 33,603 non-professional sites, accounting for 2%. Due to restrictions of language, the number of samples of target professional websites and non-target websites is limited. Meanwhile, the number of selections of strong rules is not satisfactory. Nowadays, the cores of global cyberspace security issues include internet sovereignty, cyberspace security, cyber attack, cyber crime, data leakage, and data protection. (shrink)

With their focus on human production and consumption activities, cities incur massive energy consumption and CO2 emissions. An intercity connection is a typical complex system in which the interaction between cities is crucial for developing low-carbon outputs within the urban agglomeration. This paper presents the construction of the CO2 emission network of an urban agglomeration in the Yangtze River middle reaches megalopolis, based on the gravity model. Combined with social network analysis, a multilevel analysis framework is proposed to deal with (...) the complexity, spatiality, and visualization of the CO2 emission network with reference to the network features, structural equivalence, and the rich-club phenomenon. The following results emerged: firstly, the spatial structure of the CO2 emissions was characterized by low robustness and compactness, indicating disunity among the studied cities. Secondly, there was found to be a strong correlation between regionalism and intercity connections, with geographically close cities playing a similar role in the network. Thirdly, the “rich-club” cities, including Wuhan, Changsha, Xiaogan, and Zhuzhou, dominated the connections, covering more than 87.1% of the network in the Yangtze River Middle Reaches Megalopolis.

Is it possible for historical materialism to have a specific normative basis that allows the scientific aspects of Marx’s theory to be compatible with his political philosophy and ethics? No consensus has so far been reached on this question. The debate between the normative Marx and the non-normative Marx starts with an acknowledgement of a dichotomy between facts and value. In order to resolve this dichotomy, many studies tend to place value rather than facts at the heart of their arguments (...) – they attempt to demonstrate that Marx explored issues of justice, equality, and liberty at the normative level. However, by drawing on John R. Searle’s answer to the Humean question of ‘is’ and ‘ought’, we can adopt a different approach to the study that puts facts, rather than values, at the heart of the argument. Under this approach, Marx’s analysis of the facts of estrangement, surplus-value, and the like, does not consist of factual statements that exclude value and the scientific theories that result from them. Rather, it consists of the statement of institutional facts that contain values. In Marx’s case, a fact-sensitive normative theory is fully possible. (shrink)

Today, cities account for the majority of global energy consumption and CO2 emissions. The interaction between cities is critical for regional low-carbon development. At this time, China has turned to the full opening of the carbon trading market as an important policy tool for achieving its ambitious emission reduction goals. This paper attempts to explore the spatial relationships among cities from the perspective of carbon trading. A “multiscenarios across different spatial scales” analysis framework applied to the allocation and trading of (...) CO2 emission quotas among cities in China is proposed. Based on this framework, the carbon trading networks of 182 cities in China are specifically simulated under four different scenarios, with a comparative analysis of the networks’ complexity made from different perspectives. The results of the study are as follows: firstly, significant spatial network correlations exist between the cities’ carbon trading under each scenario. Secondly, on a national scale, there are more inner connections in carbon trading networks, with stronger correlations and robustness, while the degree of connection of intercity carbon trading is higher overall on a regional scale. Thirdly, on a national scale, no obvious core nodes exist in the network, while core nodes do exist in the overall network and in each region under the regional scale. Fourthly, cities in the central region have the highest core position overall. Finally, based on the research results, practical guidance in using the framework for achieving carbon reduction, promoting economic growth, and balancing regional development, as well as the important inspiration for policy formulation, is further discussed.

Resumo: O atual ecossistema de mídia em rede é claramente caracterizado pela convergência. Recentemente, a convergência de mídia tem progredido rapidamente, tanto nos círculos teóricos quanto nas aplicações práticas, e o desenvolvimento da convergência tornou-se inevitavelmente uma tendência importante no desenvolvimento da mídia. A convergência de mídias transformou, de forma única, a ecologia das notícias, da comunicação e da opinião pública, na qual uma revisão da produção de notícias se destaca enquanto sua expressão principal. Como resultado da convergência da mídia, (...) a produção de notícias mudou de um modo linear tradicional para um modo não linear. Devido ao uso de vídeo, áudio e formas H5 de notícias, na nova mídia, além da mídia tradicional, baseada principalmente em conteúdo de texto e imagem, as reportagens de notícias são agora mais diversificadas, visualmente atraentes e inovadoras. O processo de produção de notícias mudou como resultado da convergência da mídia, tornando-se mais eficaz, adaptável e diversificado. Ao estudar o impacto da integração da mídia sobre a produção de notícias, este artigo teve, por objetivo, entender como a mídia deve ser ajustada na era da integração, de que maneira a produção de notícias deve se desenvolver e se superar, e as leis gerais da produção de notícias no processo de desenvolvimento da integração. Ao mesmo tempo, nesse contexto, a pesquisa em questão investiga o impacto da convergência da mídia na produção de notícias, delineia a maneira como a mídia pode se adaptar a cenários dinâmicos, propõe novos métodos de produção de notícias para promover o progresso da era da convergência e visa estabelecer os princípios básicos da produção de notícias no desenvolvimento integrado. Sob a tendência de digitalização, rede e informatização, o modo de produção de notícias passou por mudanças. Com o surgimento da nova mídia e a transformação gradual da mídia tradicional, o ambiente e o modo de produção de notícias também passaram por mudanças profundas. Este artigo revelou os mecanismos subjacentes e as tendências futuras dessa mudança, que podem melhorar a eficiência e a qualidade da produção de notícias, e aumentar sua competitividade em um ambiente de mídia diversificado. Ele tem um valor de referência importante para organizações de notícias, profissionais de mídia e formuladores de políticas relevantes, podendo fornecer uma base científica para a tomada de decisões.
