Background Moral courage is a recognized virtue. In the context of the COVID-19 pandemic, the master’s students of nursing (MSNs) in China have shown tenacious moral courage. Objective This study elaborates on the moral courage of Chinese MSNs through their experiences of volunteering during the pandemic. Research Design Descriptive qualitative, interview-based. Participants and Research Context Participants were nursing postgraduate students who participated in the prevention and control of the COVID-19 pandemic selected by purposeful sampling. The sample size was determined by (...) data saturation, which was reached with 10 participants. Data were analyzed using a deductive method of content analysis. Because of the isolation policy, telephone interviews were adopted. Ethical considerations After obtaining the approval of the ethical institution of the author’s school (No. 138, 30 August 2021), verbal consent was obtained before the interview with the participants. All data were processed anonymously and confidentially. In addition, we recruited participants through MSNs’ counselors, and obtained their phone numbers with their permission. Results Data analysis resulted in 15 subcategories that were subsequently grouped into 3 major categories including proceed without hesitation, the outcome of practicing moral courage, and develop and maintain moral courage. Conclusion This qualitative study is based on the special background of the COVID-19 pandemic, and the MSNs in China have shown tenacious moral courage in the work of epidemic prevention and control. Five factors led them to take action without hesitation, and six possible outcomes followed. Lastly, this study provides some suggestions for nurses and nursing students to enhance their moral courage. To better develop and support moral courage in the future, it is necessary to use different methods and multidisciplinary approaches to study moral courage. (shrink)

Background The urgency of ensuring adequate moral courage in clinical nursing practice is evident. However, currently, there are few formal intervention plans targeted at enhancing the moral courage of nurses. Aim To develop a training program for improving the moral courage of nurses using the modified Delphi method. Research design A modified Delphi study. Participants and research context From November to December 2022, a literature review and expert group discussion were conducted to develop a preliminary training plan framework. From January (...) to March 2023, a two-round Delphi survey was performed, and a consensus was reached regarding the plan through online questionnaires. Descriptive statistics were used to analyze the data. Ethical considerations This study was approved by the institutional ethics committee (No. 138, 30 August 2021). All participants provided written informed consent. Results Consensus was reached on eight themes and 33 items to strengthen the moral courage training program for nurses. Conclusions Guided by a unified goal of moral education, a multi-level and acceptable intervention plan was designed to enhance the moral courage of nurses. (shrink)

As one of the key technologies for accelerating the construction of the ubiquitous Internet of Things, demand response not only guides users to participate in power market operations but also increases the randomness of grid operations and the difficulty of load forecasting. In order to solve the problem of rough feature engineering processing and low prediction accuracy, a short-term load forecasting model of LSTM neural network considering demand response is proposed. First of all, in view of the strong randomness and (...) complexity of input features, the weighted method is used to process multiple input features to strengthen the contribution of effective features and tap the potential value of features. Secondly, an improved genetic algorithm is used to obtain the best LSTM parameters; finally, the special gate structure of the LSTM model is used to selectively control the influence of input variables on the model parameters and perform load forecasting. The experimental results show that the research has high prediction accuracy and application value and provides a new way for the development of power load forecasting. (shrink)

Milan Kundera is one of the most influential writers in contemporary world literature. In his novels, there are many symbolic metaphors related to numbers, dreams, and animals. Combing through the plots of Kundera’s novels, we can discover that among all the numbers, seven and twenty are used most frequently. These two numbers have rich metaphorical meanings. Besides, there are many other digital metaphors in Kundera’s novels, including 6, 4, etc. Apart from number symbols, Kundera has also inserted various kinds of (...) dream symbols in his artistic creation. For Kundera, dreams are not just an individual’s physical and psychological activities, but also a continuation and supplement of real life. It can be concluded that dream narration is a perfect medium for the author to express his philosophical ideology. In addition, dream symbols also serve as an important medium for Kundera to demonstrate narrative skills and present important themes. In Kundera’s novels, animal symbols are integrated with the plots, revealing the personal traits of the relevant characters, and mirroring their spiritual world at the same time. Besides, Kundera also expressed his ecological ethics through the narration of animals’ death. In conclusion, the metaphorical meanings of different symbols in Kundera’s novels play an active role in highlighting the themes, revealing the inner thoughts of the characters, showing the special features of the characters, and expressing the author’s philosophical thoughts. These symbols help Kundera to break the limitations of time and space, which has become an important part of his polyphonic art. What’s more, Kundera has also tried to expand the original metaphorical meanings of these symbols to create some new poetic meanings. (shrink)

Mining time series data is of great significance in various areas. To efficiently find representative patterns in these data, this article focuses on the definition of a valid dissimilarity measure and the acceleration of partitioning clustering, a common group of techniques used to discover typical shapes of time series. Dissimilarity measure is a crucial component in clustering. It is required, by some particular applications, to be invariant to specific transformations. The rationale for using the angle between two time series to (...) define a dissimilarity is analyzed. Moreover, our proposed measure satisfies the triangle inequality with specific restrictions. This property can be employed to accelerate clustering. An integrated algorithm is proposed. The experiments show that angle-based dissimilarity captures the essence of time series patterns that are invariant to amplitude scaling. In addition, the accelerated algorithm outperforms the standard one as redundancies are pruned. Our approach has been applied to discover typical patterns of information diffusion in an online social network. Analyses revealed the formation mechanisms of different patterns. (shrink)

In the former 20 years, professional identity has arisen as a different study domain in the area of language instruction and education. Educators’ professional identity frames educators’ explanation of their functions, academic changes, and alterations in syllabi, class exercises, utilization of approaches and strategies, and their connection to other problems in the academic setting. Also, well-being is one of the elements in which its influence and connection with identity are noted in various studies. However, their roles in professional development have (...) not been examined; hence, this review of literature aimed to investigate the role of these constructs in professional development which is regarded as a noteworthy aspect of teacher quality. In a nutshell, some implications are proposed for the scholastic stakeholders. (shrink)
