Despite research establishing emojis as sites of critical racial discourse, there is a paucity of literature examining their importance in the increasingly popular context of mobile payments. This is particularly important as new forms of social payment platforms such as Venmo bridge the seamlessness of mobile payments with the vibrant communicative practices of social networks. As such, they provide a unique medium to examine how emojis are used within the context of digital consumption, and by extension, self-representation. This study analyzes (...) approximately 325 million public transactions on the U.S. payment platform Venmo to understand whether emoji usage in mobile payments is more hedonic or utilitarian. We then explore how race is represented across emoji usage on Venmo via tone-modified emojis, a subset of emojis whereby users can choose a skin tone. We found that while emojis in general are used for more hedonic purposes than utilitarian ones, darker tone-modified emojis indicate a proportionately higher use in hedonic consumption as compared to lighter tone-modified emojis, and also show a higher representation of utilitarian categories in transactions. Thematic analysis revealed that subsets with darker tone-modified emojis have a greater lexical variety and engage in more playful uses of emoji in mobile payments. (shrink)

In recent years, misinformation sharing has become the focus of public debate and academic research. We aim to explore whether individuals prefer to share accurate information or not, and discover what factors increase people’s preferences for sharing accurate information. Combining behavioral economics experiments and psychology experiments, we construct “an information search—information sharing—information feedback experiment” to examine individuals’ behavior of sharing accurate information and its influencing factors. A total of 210 students are recruited for the laboratory experiment. Our results show that (...) when individuals can control the accuracy of the information they obtain through their efforts, they are more willing to share accurate information with others. We also find that positive feedback from information receivers can promote the accuracy of information shared by individuals, and this effect works through reciprocity norms. Individuals with higher reciprocity are more willing to share accurate information, especially in the treatment with the role of reciprocity norms enhanced by feedback. These findings indicate that individuals who are willing to obtain accurate information prefer to share information, and information feedback can enhance this preference through reciprocity norms. This study captures individuals’ behavior and preference characteristics with regard to the accuracy of the information they share in the era of highly developed network interaction. (shrink)

This paper addresses the adaptive asymptotic tracking control problem for nonlinear systems whose virtual control gains are unknown nonlinear functions of system states. Only in the first step, the Nussbaum gain technique is utilized to handle the uncertain virtual control gain. In the remaining steps, virtual control gains are dealt with by constructing novel control laws without the approximation of the uncertain nonlinear functions and external disturbances by neural networks or fuzzy logic. New adaptive laws are defined to compensate for (...) unknown virtual control gains, uncertain parameters, and external disturbances. Finally, an adaptive tracking controller is designed and applied to the control of a 3-order robot system, which guarantees the boundedness of all the signals in the closed-loop system and asymptotic stability of the tracking error.

Crowdsourcing innovation community has become an important platform for enterprises to gather group wisdom. However, how the crowdsourcing innovation community plays a reference role in creative crowdsourcing participation is unclear. Based on the reference group theory, taking online impression management as the explanatory framework, this study explores the impact of crowdsourcing innovation community reference on the creative territory behavior, and the differences in the crowdsourcing innovation community reference effect among members of different community age groups. A total 524 valid two-stage (...) questionnaires were collected. The empirical analysis results show that under the influence of informational reference and utilitarian reference of the crowdsourcing innovation community, community members are significantly more likely to adopt acquired impression management than defensive impression management ; under the influence of value expressive reference of the crowdsourcing innovation community, the possibility of adopting DIM behavior is significantly greater than that of adopting AIM behavior; compared with DIM behavior, AIM behavior has a more inhibitory effect on creative territory behavior. Interestingly, there are different community reference effects among members of different community age groups. In particular, the positive contribution of the elder members is not as good as that of the newcomers. The above research conclusions not only confirm the influence of crowdsourcing community reference on crowd participation decision making but also provide theoretical and practical enlightenment for exploring the cooperation mechanism of crowdsourcing innovation.

This article proposes an Analytic Hierarchy Process Dempster-Shafer and similarity-based network selection algorithm for the scenario of dynamic changes in user requirements and network environment; combines machine learning with network selection and proposes a decision tree-based network selection algorithm; combines multiattribute decision-making and genetic algorithm to propose a weighted Gray Relation Analysis and genetic algorithm-based network access decision algorithm. Firstly, the training data is obtained from the collaborative algorithm, and it is used as the training set, and the network attributes (...) are used as the attribute set, and the continuous attributes are discretized by dichotomization, and the attribute that can make the greatest information gain is selected as the division feature, and a decision tree with strong generalization ability is finally obtained, which is used as the decision basis for network access selection. The simulation results show that the algorithm proposed in this thesis can effectively improve user service quality under three services, and the algorithm is simple and effective with low complexity. It first uses AHP-DS hierarchical analysis to establish a recursive hierarchy for the network selection problem and obtains the subjective weights of network attributes through the judgment matrix. Then, it uses a genetic algorithm to adjust the subjective weight, defines the fitness function in the genetic algorithm-based on gray correlation analysis, adjusts the weights of the selection operator, crossover operator, and variation operator in the genetic algorithm, and gets the network with the largest fitness as the target network, which can effectively improve the user service quality.

From 2011 to 2015, it is the period of a rapid and fruitful development for feminist philosophy studies in China. According to the database of China National Knowledge Internet (CNKI), there are 377 articles with the key word of feminist philosophy to have been published in a number of journals in the period. Comparing to 267articles that were published in 2006-2010, the number of periodical articles increases 41%. This not only shows the concern and participation for Chinese scholars to study (...) in feminist philosophy, but also embodies more systematically and richly in research methodologies and subjects, as well as their practical applications. This paper will be a review of the study of Chinese Feminist Philosophy under 8 sub-tittles, and try to analyze the achievement of feminist philosophy in the years 2011—2015 and look forward to the future possibilities for feminist philosophy studies in China.

LANGUAGE NOTE | Document text in Chinese; abstract also in English. COVID-19疫情的爆發，突顯出公共健康倫理中自主性與公共健康之間的緊張關係。以“publichealth”、“ethics”、“autonomy”為主題詞在WebofScience核心合集數據庫中 進行文獻收集，借助CiteSpace6.1軟件進行信息可視化分析，發現2020年1月1日至2022年5月14日期間，生命倫理/公共健康倫理領域對於“自主性”概念的討論大體上集中在“知情同意”、“健康保 健政策"、“健康質量”、“信息技術”和“老年歧視/老年群體”範圍。本文在此基礎上提煉分析COVID-19疫情中的四個“自主性‘‘難題 如何避免以公共健康/公共利益為名過度限制自主性、在數字技術應用中如何保障自主性、如何保障老年群體的自主性和生命權，如何通過促進自主性來推動公共健康目標的實現。COVID-19疫情是一個重塑公共健康倫理 自主性概念的歷史契機。冷酷的病毒已經作為一種媒介把人類的命運緊密地聯繫起來，而基於關懷倫理和共同體倫理重塑的自主性概念則有望給疫情下的世界帶來團結、温暖和希望。 In the field of public health ethics, the COVID-19 pandemic has highlighted the tension between autonomy and public health. Using CiteSpace 6.1 software and information visualization analysis, we performed a search of literature in the Web of Science core collection database using thematic words such as “public health”, “ethics” and “autonomy”, we found that from January 1, 2020 to May 14, 2022, discussions on the concept of “autonomy” (...) within the field of bioethics/public health ethics were generally focused on the following topics: “informed consent”, “health care policy”, “health quality”, “information technology”, “ageism” and “elderly group”. In this paper, we distill and analyze four controversial issues: how can we avoid excessive restrictions on autonomy in the name of public health/public interest? How can we protect autonomy when using digital technology? How can we protect the autonomy and rights of the elderly? How can we advance the goals of public health by promoting autonomy? The COVID-19 pandemic is a unique historical opportunity to reshape the concept of autonomy within the field of public health ethics. Although the virus has bound the fate of humanity together, a reinvented concept of autonomy based on care and community ethics holds the promise of bringing solidarity, comfort, and hope to the world in the midst of the pandemic.
