Engineering involves systematic, complex, socio-technological activities, with both benefits and risks for the public. Most feasibility studies focus on the technological, economic, and material (resources and power) aspects. However, this ignores public acceptability and can give rise to public resistance and non-cooperation, which in turn undermines credibility of the government, enterprises, engineers, and technicians. As a result, some engineering projects are impeded or forced to relocate at huge costs in natural and financial resources. In light of such situations, it is necessary to incorporate acceptability studies into engineering feasibility studies. From the perspective of socio-technical systems, we first analyze the deficiency in feasibility studies and point out that as a concept, feasibility involves not only the instrumental aspect of practice, but also ethical and cultural dimensions. Then we argue that feasibility also connotes acceptability. On this basis, feasibility is revealed to presuppose social legitimacy, which is not the same as simple acceptance, but involves a synthesis of facts and opinions. Finally, through the examination of multiple-value conflicts and the public’s limited understanding of engineering, we suggest that feasibility studies should be set in specific cultural contexts and follow problem-solving procedures that involve democratic negotiations or forums.

Labels provide a quick and effective solution to obtain people interesting content from large-scale social network information. The current interest label extraction method based on the subgraph stream proves the feasibility of the subgraph stream for user label extraction. However, it is extremely time-consuming for constructing subgraphs. As an effective mathematical method to deal with fuzzy and uncertain information, rough set-based representations for subgraph stream construction are capable of capturing the uncertainties of the social network. Therefore, we propose an effective approach called RS_UNITE_SS, which is suitable for large-scale social network user interest label extraction. Specifically, we first propose the subgraph division algorithm to construct a subgraph stream by incorporating a rough set. Then, the algorithm for user real-time interest label extraction based on upper approximation is proposed by using sequentially characteristics of the subgraph. Empirically, we evaluate RS_UNITE_SS over real-world datasets, and experimental results demonstrate that our proposed approach is more computationally efficient than existing methods while achieving higher precision value and MRR value.

The system reachability set is calculated by covering all possible behaviours of the system through a finite number of simulation steps to ensure that the system trajectory stays within a set safety region. In this paper, the theory of the game method is applied to the design of the controller, a very small controller is designed, and good control results are obtained by simulation. The system gradually shows a divergent trend and cannot achieve stable control. A multihop channel reservation Medium Access Control protocol based on a parallel mechanism is proposed. The multihop channel reservation mechanism is proposed based on periodic node sleep, and the node uses the reservation frame to make the reservation of the channel and transmits the data according to the reservation information; the parallel mechanism is used to make the reservation information and data transmission simultaneously.

Resumen: La ola creciente de la China-chic proporciona un nuevo modo de presentación para la excelente cultura tradicional, permitiendo a la gente volver a ser testigo de la vitalidad innovadora de la cultura local y brindando una nueva vía de creación para la cultura popular rural. En este contexto, el diseño con el tema de la cultura popular rural se enfrenta tanto a nuevas oportunidades como a nuevos retos. En este artículo, basado en el estudio de caso del diseño folclórico rural del Templo señorial del condado de Hexian, en la provincia de Anhui, se analizan brevemente la relación dialéctica y la práctica de la herencia y la innovación en el trabajo de diseño bajo el trasfondo del China-chic. Se propusieron estrategias de diseño innovador para revitalizar el énfasis de la gente en la cultura tradicional, reavivar la atención de la gente hacia la cultura tradicional y ampliar la vía de diseño innovador de una vía de comunicación de la cultura tradicional para promover la transformación creativa y el desarrollo innovador de la cultura tradicional china.

Social semiotics is now widely regarded as one of the leading research areas. This study is the first attempt to present a holistic overview of social semiotics based on the data in the Web of Science core collection database from 2001 to 2020. The study investigates, among other issues, social semiotics’ publishing tendency, the most productive authors, countries, institutions, and hotspots. The results exhibit a steady rise in its publications and citations. The current analysis verifies the growing quantitative and qualitative research contributions and influences of this field. Furthermore, what the journals focus on are the innovative and contemporary themes, manifested predominantly in sign, multimodality, gender, experimental semiotics, advertising, culture, and social media, which involve a wide range of methodologies to make the research more acceptable and constructive. These results are expected to offer refreshing insights that inspire scholars in formulating scientific agendas and advising their research strategies, thereby facilitating substantial contributions to the domain.

The popularity of social media, such as WeChat and Weibo in China, has provided an opportunity to develop social commerce. Although shopping through social commerce platforms is widely favored by consumers, the factors affecting consumers’ decision-making behavior in the social commerce environment remain unclear. Therefore, from the perspective of the stimulus–organism–response theory, we construct a consumer repurchase decision model in the social commerce environment and analyze the influencing mechanism of social commerce features on perceived value and consumers’ repurchase intention. The empirical results found that social commerce features are positively related to the generation of perceived value, which in turn drives consumers to form repurchase intentions. We also found some mediating effects of perceived value. The study’s conclusions clarify the intrinsic influence mechanism of social commerce features on consumers’ perceived value and repurchase intentions. In addition, it can provide some theoretical guidance for future research and business.

The Western approaches on energy justice mostly link energy access to basic need and rights of individuals. These approaches are mainly based on the rights-justice theory of traditional political philosophy. Though Sovacool et al. introduce the dimension of moral philosophy and ethical responsibility into the study of energy justice, their standpoint remains individual freedom, equality, and responsibility. However, energy issues are not only a matter of individual rights and responsibilities, nor are they only problems of the distribution and commitment of the accessibility and environmental consequences of energy consumption. From the very beginning, energy issues involve the issue of inter-subject relationships, involving both the responsibility of individuals and of collective subjects. Therefore, it is necessary to jump out of the traditional mode of thinking of individual rights theory and individual responsibility.Based on the traditional Chinese philosophical ethical Chinese ethical resourcesCommunity of shared future for mankindChinese philosophical ethical resources, mainly the Confucian thoughts on hexie and yi, the “Tianxia” view, and the reflections from the tradition of community both from the West and East, this article links energy justice to the construction of community with a shared future for mankind and puts forward that the foundation of Community of shared future for mankindenergy justice lies in how to construct the relationship between the subjects of justice in the community with a shared future for mankind. Through cases of Community of shared future for mankindYulin and global carbon emissions about energy justice, we propose a holistic perspective on energy justice inspired by the idea of the community with a shared future for mankind, and then point out that we should deal with the four major relations involved in the complete process of energy acquisition, distribution, utilization, and post-processing, in order to build a just Community of shared future for mankindenergy system. Finally, we propose three possible strategies to deal with issues of energy justice, that is, specific strategy, real-time strategy, and holistic strategy, which may shed some light on the global issues of energy justice.
