One purpose of cognitive diagnostic model is designed to make inferences about unobserved latent classes based on observed item responses. A heuristic for test construction based on the CDM information index proposed by Henson and Douglas has a far-reaching impact, but there are still many shortcomings. He and other researchers had also proposed new methods to improve or overcome the inherent shortcomings of the CDI test assembly method. In this study, one test assembly method of maximizing the minimum inter-class distance (...) is proposed by using mixed-integer linear programming, which aims to overcome the shortcomings that the CDI method is limited to summarize the discriminating power of each item into a single CDI index while neglecting the discriminating power for each pair of latent classes. The simulation results show that compared with the CDI test assembly and random test assembly, the new test assembly method performs well and has the highest accuracy rate in terms of pattern and attributes correct classification rates. Although the accuracy rate of the new method is not very high under item constraints, it is still higher than the CDI test assembly with the same constraints. (shrink)

This study investigated the status of research integrity knowledge among dental undergraduates from 34 Chinese universities in 5 key demographic regions. Questionnaires regarding the status of research integrity, including perception, attitude, and firsthand experience of scientific research integrity, were distributed to dental undergraduates of 34 Chinese universities. These universities were from 5 key demographic regions of China, i.e., eastern, western, northern, southern, and central. The questionnaires filled out by 1514 participants were further analyzed. The results showed that among the participants, (...) nearly 70% acquire scientific integrity knowledge through courses, as well as ideological and political education, while the remaining students acquire scientific integrity knowledge through other means, such as books and conferences. From the attitude perspective, most students (80-90%) oppose scientific misconduct. However, a few students also have an insufficient understanding of scientific misconduct and still need to improve their scientific research integrity training further. We also found that the research integrity training and the surrounding research environment affect students' attitudes and self-behavior regarding scientific integrity. Our findings indicate that the ethical academic and research environment, implementation of scientific integrity courses in the curriculum, and proper supervision are vital in improving scientific research integrity knowledge in dental undergraduates in Chinese universities.

Most discussions of racial fetish center on the question of whether it is caused by negative racial stereotypes. In this paper I adopt a different strategy, one that begins with the experiences of those targeted by racial fetish rather than those who possess it; that is, I shift focus away from the origins of racial fetishes to their effects as a social phenomenon in a racially stratified world. I examine the case of preferences for Asian women, also known as ‘yellow (...) fever’, to argue against the claim that racial fetishes are unobjectionable if they are merely based on personal or aesthetic preference rather than racial stereotypes. I contend that even if this were so, yellow fever would still be morally objectionable because of the disproportionate psychological burdens it places on Asian and Asian-American women, along with the role it plays in a pernicious system of racial social meanings.

This chapter distinguishes between two concepts of moral responsibility. We are responsible for our actions in the first sense only when those actions reflect our identities as moral agents, i.e. when they are attributable to us. We are responsible in the second sense when it is appropriate for others to enforce certain expectations and demands on those actions, i.e. to hold us accountable for them. This distinction allows for an account of moral responsibility for implicit bias, defended here, on which (...) people may lack attributability for actions caused by implicit bias but are still accountable for them. What this amounts to is leaving aside appraisal-based forms of moral criticism such as blame and punishment in favor of non-appraising forms of accountability. This account not only does more justice to our moral experience and agency, but will also lead to more effective practices for combating the harms of implicit bias. (shrink)

Moral agency is limited, imperfect, and structurally constrained. This is evident in the many ways we all unwittingly participate in widespread injustice through our everyday actions, which I call ‘structural wrongs’. To do justice to these facts, I argue that we should distinguish between summative and formative moral criticism. While summative criticism functions to conclusively assess an agent's performance relative to some benchmark, formative criticism aims only to improve performance in an ongoing way. I show that the negative sanctions associated (...) with summative responses are only justifiably imposed under certain conditions when persons exercise their agency wrongly — conditions that do not always hold for structural wrongs. Yet even in such cases we can still use formative responses, which are warranted whenever agents fall short of moral ideals. Expanding our repertoire of moral criticism to include both summative and formative responses enables us to better appreciate both the powers and limitations of our agency, and the complexity of moral life.

Now that society is in a period of transition, the lack of norms for moral values is becoming an increasingly serious issue. People in commerce talk about commerce, and those "going out to sea" talk about the sea.

With the continuous development and improvement of Internet media technologies in China, the influence of livestream e-commerce is becoming increasingly prominent, and an increasing number of people are engaging in consumption activities in this field. It is important to study consumer stickiness in livestream e-commerce to promote economic structure adjustment and innovation-driven development. Therefore, in this study, we adopted the expectation confirmation theory as the theoretical framework and analyzed the ECT and stickiness. The study considered satisfaction as the previous influencing (...) factor of user and consumer stickiness, replaced the continuance intention in the expectation confirmation model with consumer stickiness as the explanatory variable, introduced the variable of perceived playfulness as the value perception after user experience, and established a consumer stickiness factors model. A total of 262 valid questionnaires were collected in this study, and SmartPLS analysis along with interviews were used to justify the limitations of data analysis. The results of the study demonstrated a significant effect of perceived usefulness and confirmation on satisfaction, a significant effect of confirmation on perceived usefulness, a significant effect of satisfaction on stickiness, and a significant effect of confirmation on perceived playfulness. Based on findings from the data analysis and interviews, we further proposed rationalized recommendations, and aimed to provide some theoretical guidance for future research on live streaming.

The virtual brand community has become an important marketing tool for companies. A successful brand community marketing strategy should attract a large number of consumers. Although past studies have revealed consumer motivations for participating in virtual brand communities, they fail to answer an important question: Why is it so easy for some virtual brand communities to attract users while others have such difficulty? In this study, product characteristics are hypothesized to be important factors that determine consumer motivation to participate in (...) brand communities. Product characteristics can directly affect how actively consumers participate in brand communities. The results of questionnaires show that product complexity, product symbolism, and product satisfaction have a positive influence on consumers’ willingness to participate in brand communities. Notably, the duration of product use has a regulating effect on the influence of product satisfaction and product symbolism. A long period of product use weakens the influence of product satisfaction on consumers’ willingness to participate in brand communities. On the contrary, a long period of product use strengthens the influence of product symbolism on consumers’ willingness to participate in brand communities. This study enriches the literature on brand community participation and has implications for companies that aim to utilize brand communities for marketing. (shrink)

Young children judge that violations of ordinary, causal constraints are impossible. Yet children’s religious beliefs typically include the assumption that such violations can occur via divine agency in the form of miracles. We conducted two studies to examine this potential conflict. In Study 1, we invited 5- and 6-year-old Colombian children attending either a secular or a religious school to judge what is and is not possible. Children made their judgments either following a minimal prompt or following a reminder of (...) God’s extraordinary powers. Irrespective of their education, and whether or not they had been reminded of God’s extraordinary powers, children systematically judged violations of ordinary, causal constraints to be impossible. In Study 2, we asked if more extensive reminders of God’s special powers would prompt religious children to say that the impossible can happen. Five- and 6-year-old Colombian children attending either a secular or a religious school were presented with narratives in which the protagonist desired an ordinarily impossible outcome. In half the stories, the protagonist prayed to God for the desired outcome. Irrespective of education and of whether the protagonist prayed, children systematically concluded that the desired outcome would not occur and justified that conclusion by reference to ordinary causal constraints. Nevertheless, in a minority of their replies children did assert that violations of ordinary causality are possible. Overall, irrespective of their religious education, young children judge that events rarely deviate from their natural course; only occasionally do they acknowledge exceptions. (shrink)

The transition from classical physics to quantum mechanics has been mysterious. Here, we mathematically derive the space-independent von Neumann equation for electron spin from the classical Bloch equation. Subsequently, the space-independent Schrödinger–Pauli equation is derived in both the quantum mechanical and recently developed co-quantum dynamic frameworks.

The green development level reflected in the green finance index and the evaluation of the degree of green development in smart cities have important practical effects on economic transformation. For promoting the transformation and upgrading of finance, we select 2013–2019 data and construct a distributed lag model to analyse the important role played by green finance and financial technology in the construction of smart cities. In the paper, we find green finance promotes the construction of smart cities, and only it (...) will not appear until nine months late. Financial technology has an opposite impact on the construction of smart cities, this is mainly because the research and marketization of financial technology are higher, and the cost is also higher. This influence will appear in the next 14 months. (shrink)

Artificial intelligence is regarded in the context of the tasks that are delegated to it during the development of technical projects and the features of the implementation of tasks that must be performed in real time without the possibility of interruption. The relevance of the study is determined by the fact that artificial intelligence sees as its main task the formalisation of decision-making with little or no human involvement. The basis of the methodological search are biological and prognostic methods. The (...) current stage of development of socio-humanitarian technologies, and in particular, systems with artificial intelligence, prompts people to conduct such socio-technical projects, for the implementation of which the properties of the human biological brain are no longer enough. The result of research on artificial intelligence is the desire to understand the work of the human brain, to reveal the secrets of human consciousness and the problem of creating machines with a certain level of human intelligence. The novelty of the study is determined by the fact that the understanding of artificial intelligence is primarily aimed at creating an environment that can distinguish artificial intelligence from the entire array of technological devices not only as a platform of knowledge and program code. The practical significance of the study is determined by the necessity for standardisation and the formation of attitudes and the acceptability of the use of artificial intelligence in tasks that will subsequently affect social development.
