BackgroundCompassion fatigue is often associated with moral distress in the nursing practice among registered nurses. Moral resilience is an important ability to maintain, restore, or promote their physical and mental health in response to ethical dilemmas in nursing. Moral resilience can be utilized as a potential solution to aid registered nurses in effectively managing compassion fatigue.AimTo identify latent profiles of moral resilience among registered nurses and to explore the relationships of these profiles with compassion fatigue.Research designFrom August 2022 to December (...) 2022, 569 nurses were recruited in two general hospitals, in China. A Rushton Moral Resilience Scale and the Chinese version of Compassion Fatigue—Short Scale were given to the participants. A latent profile analysis was conducted to explore moral resilience latent profiles. Predictors of profiles membership was evaluated using multinomial logistic regression analysis, and the compassion fatigue scores of each latent profile were compared using a one-way analysis of variance.Ethical considerationsWe obtained ethical approval from the Institution Review Board of Xiangya School of Nursing, Central South University (IRB No. E202293, approved 15/July/2022).ResultsA four-profile moral resilience model best fit the data. Different levels and shapes differentiated the four profiles: high moral resilience (28.7%), moderate moral resilience (52.3%), low responses and high efficacy (16.2%), and low moral resilience (2.8%). Nurses with bachelor’s degrees were more likely to belong to the high moral resilience ( OR = 0.118, p =.038) and moderate moral resilience ( OR = 0.248, p =.045); Nurses who were divorced or separated ( OR = 11.746, p =.025) and very dissatisfied with their work ( OR = 0.001, p =.049) were more probably belonging to low moral resilience. Nurses who had received ethical training in the hospital were more likely involved in high moral resilience ( OR = 5.129, p =.003) and low responses and high efficacy ( OR = 5.129, p =.003). In each profile of moral resilience, compassion fatigue was experienced differently by the participants ( F = 13.05, p <.001).ConclusionsDeveloping and implementing interventions tailored to each nurse’s moral resilience profile would maximize interventions’ effectiveness and reduce nurses’ compassion fatigue.

There is controversy as to whether children with developmental language disorder (DLD) and those with high-functioning autism plus language impairment (HFA-LI) share similar language profiles. This study investigated the similarities and differences in the production of Chinese negative sentences by children with DLD and children with HFA-LI to provide evidence relevant to this controversy. The results reflect a general resemblance between the two groups in their lower-than-TDA (typically developing age-matched) performance. Both groups encountered difficulties in using negative markers, which suggests (...) that they might be impaired in feature agreement. Slight differences were detected between the two groups. Specifically, children with DLD experienced difficulties with the agreement on the feature [+telic] and that on the feature [+dynamic], while children with HFA-LI had difficulties with the agreement on the feature [+dynamic] and that on the feature [−dynamic]. This study supports the idea of a common symptomatology for the two disorders. More importantly, it suggests that these two disorders, DLD and HFA-LI, are not altogether the same in terms of language impairment. This paper concludes that general labels should not be simply attached to any children with language disorders. Instead, atypical language is very worthy of further analysis in the categorization of language disorders. (shrink)

In this study, we are concerned with how agents can best amalgamate their private information about a binary state of Nature. The agents are heterogeneous in their “ability”, the quality of their private information. The agents cannot directly communicate their private information but instead can only vote between the two states. We first describe possible methods of sequential majority voting, and then we analyze a particular one: the first n-1\documentclass[12pt]{minimal} \usepackage{amsmath} \usepackage{wasysym} \usepackage{amsfonts} \usepackage{amssymb} \usepackage{amsbsy} \usepackage{mathrsfs} \usepackage{upgreek} \setlength{\oddsidemargin}{-69pt} \begin{document}$$n-1$$\end{document} jurors vote (...) simultaneously and, in the case of a tie, the remaining juror has the casting vote.

Drug abuse has been and continues to be, a common social issue worldwide, yet the efficiency of widely adopted sweeping speech for anti-drug campaigns has proven inefficient. To provide students with a safe and efficient learning situation related to drug refusal skills, we used a novel approach rooted in a serious learning game and concept map during a brief extracurricular period to help students understand drugs and their negative effects. The proposed game-based situational learning system allowed all students to participate (...) simultaneously and individually in multiple scenarios of drug temptation posed by peers and classmates to practice responding and refusing drugs in school and community settings. Moreover, to explore whether different personality traits result in different anti-drug responses, we used a serious game to conduct an anti-drug experiment on 53 junior middle school students aged 13–15. Each participant’s decision-making process was recorded in the serious game as behavioral patterns for lag sequential analysis. The outcomes revealed seven behavioral patterns including differentiation, acceptance, effective and ineffective responses, effective and ineffective solution-seeking, and failure to refuse. The GSEQ which is a computer program for analyzing sequential observational data was used. The results indicated the following: Neuroticism was performed at a relatively low level under the guidance of a concept map. “Neuroticism” was associated with the lowest risk of accepting drugs. Students with “openness to experiences” were at high risk of accepting drugs. Almost all personality behavioral transition diagrams showed that failure to refuse drugs was followed by inefficient seeking of help and inefficient refusal. These findings provide reference points for designing adaptive anti-drug education programs. (shrink)

Our understanding of the complexity of the oral biome and of the role of the various constituent bacteria in the aetiology of dental disease is growing. Probiotics and their relationship with prebiotics, as well as other microbiome‐based interventions, could be useful in preventing and treating dental disease and in promoting oral health. However, given the promise and early stage of this treatment approach, there are also a number of ethical, social and regulatory issues associated with innovative probiotic therapy. In this (...) article, a brief update is given on contemporary theories of the aetiology and management of the two commonest dental diseases, and on the roles of pre‐ and probiotics and oral biome transplant in the management of these diseases. The focus is primarily on four core issues: informed consent, risk–benefit assessment, how to determine suitable healthy donors, and commercialization and regulation. We discuss the safety and benefits of oral probiotics, not only concerning the products and quality control during their manufacture, but also regarding the depth of public knowledge about this topic. We point out that the requirement of listing ingredients honestly might be insufficient, and that the prevalent rhetoric of ‘natural’ and ‘organic’ as well as some health claims in the translational, innovative probiotic industry and markets are themselves misleading and should be carefully scrutinized. Finally, we suggest an ethical imperative to find a balance between scientific research and industry, and public health in the regulation of probiotics. (shrink)

Travelling internationally to acquire medical treatments otherwise unavailable or inaccessible in one’s home country is not a novel concept. Conventionally, such medical travel largely entailed patients from developed countries or wealthy patients from the developing world seeking care in Western facilities like the Mayo Clinic in the U.S. and myriad private clinics along Harley Street in London, England. What is different about the topical phenomenon known as “medical tourism” is the growing trend of health services export in the opposite direction. (...) The number of patients travelling from the developed world to low- and middle-income countries for treatments has ballooned in recent years, primarily driven by difficulties with accessing affordable care at home. According to a liberal estimate by the Deloitte Center for Health Solutions, the number of Americans travelling abroad for care rose from 750,000 in 2007 to 1.6 million in 2012. On the flip side, Thailand reportedly treated a total of 1.3 million foreign nationals in 2007, which represented a 16% leap from 2001. (shrink)

Objective To determine the knowledge and attitudes of healthcare personnel regarding the provision of non-beneficial futile care in the intensive care units at the major public hospitals in Trinidad and Tobago. Method Prospective data collection was done using a questionnaire administered to the medical and nursing staff of the intensive care units. The questionnaire was designed to capture the opinions regarding the futile care offered to terminally ill patients at the intensive care units. The responses were based on a five-point (...) Likert scale. The influence of factors such as age, gender, duration of work experience, religious belief, ethnicity, occupational category and educational status on the responses were analysed. Results A total of 274 completed responses were obtained from doctors and nurses. The frequency with which the respondents encountered ethical or legal problems in the intensive care unit varied widely from ‘daily’ to ‘yearly’. The majority felt that knowledge of ethics is important, and only 32% knew the legal issues pertaining to their work. Eighty percent of doctors and nurses had no knowledge of an existing Hospital Ethics Committee and its role in ethical dilemmas. Although 62% said their decisions regarding futile care will be influenced by their scientific knowledge, only 32% agreed to withdraw care. Eighty percent said that the government should pass appropriate laws regarding withdrawal of futile care. Conclusions Most healthcare providers in intensive care unit are not knowledgeable in the ethical and legal issues of non-beneficial futile care. There is a need to devise means to bring awareness and educate intensive care unit healthcare providers in this subject. (shrink)

This study attempts to answer the question why Confucianism, the dominant “teaching” among the Three Teachings, is not a religion in contemporary China, unlike the other two “teachings,” Buddhism and Daoism. By examining this phenomenon in the social-historical context, this study finds its origin in Orientalism. The Orientalist conceptualization of religion became part of the New Culture discourse at the turn of the twentieth century. While China has undergone tremendous social changes over the past century, the old discourse remains.

Background: Chinese Taoist cognitive therapy (CTCT), a culture-oriented psychological therapy for Chinese mental well-being, has been proposed for decades. However, the evidence for its effects is unclear. This study aimed to systematically assess the effect of this therapy on symptoms of depression and anxiety in Chinese adults. Methods: Relevant studies were searched from major electronic databases through November 2018 without language limits. Several search terms used include “anxiety” OR “depression” AND “Taoism” OR “Daoism” OR “Chinese Taoist Cognitive Therapy”. A total (...) of 11 clinical trials focusing on CTCT were included in this meta-analysis. Random-effects meta-analytical models were conducted. Heterogeneity and publication bias were also explored. Results: Eight clinical trials for 580 subjects were included. The majority of these studies explored samples with depressive symptoms. Overall, CTCT significantly reduced depressive symptoms with a small positive effect (SMD = 0.16, 95% CI: -0.36-0.68). Medium-to-large effect sizes were observed across individuals with clinical or nonclinical depression and chronic physical diseases (SMD = 0.70, 95%CI: 0.27-1.13 and SMD = 0.72, 95%CI: 0.09-1.35, respectively). However, the effectiveness for anxiety symptoms remains debatable. Conclusions: Our findings hold promise that CTCT can help reduce depressive symptoms in Chinese adults, including patients with chronic physical diseases and clinical or nonclinical depression. Our findings may be generalized to Chinese communities in other countries. (shrink)

Purpose/Significance. This study aims to explore the differences in the effectiveness of rumor refutation dissemination on government micro-blogs and to identify factors that may lead to such differences, so as to provide reference for the management of emergencies and to improve the effectiveness of rumor refutation. Methodology/Procedure. Using Octopus software to collect data from thirty government micro-blogs, the number of retweets, likes, and comments were used as indicators of the effectiveness of refutation dissemination and different levels of government micro-blogs were (...) used as moderating variables to construct a regression model of the effect of content features and text features on refutation dissemination. The regression model was constructed to test the moderating effects of micro-blog content and text features on the effectiveness of micro-blog refutation. Results/Conclusions. The empirical results show that whether a micro-blog is from the region or not and whether a micro-blog has a title or not have a significant effect on the effectiveness of micro-blog refutation dissemination. Therefore, refutation strategies such as combining layers, giving equal importance to content and form, and focusing on originality can be adopted to enhance the refutation effect of government micro-blogs.

While the traditional economic wisdom believes that an individual will become better off by being given a larger opportunity set to choose from, in this paper we question this belief and build a formal theoretical model that introduces decision costs into the rational decision process. We show, under some reasonable conditions, that a larger feasible set may actually lower an individual’s level of satisfaction. This provides a solid economic underpinning for the Simon prediction.

The intracellular multiprotein complex β‐catenin destruction complex plays a key role in Wnt/β‐catenin signaling. Wnt stimulation induces the assembly of the receptor‐associated signalosome and the inactivation of the destruction complex, leading to β‐catenin accumulation and transcriptional activation of the target genes. The core components of the destruction complex include Axin, APC, GSK3β, CK1α and other proteins. Recent studies demonstrated that Axin and APC undergo liquid–liquid phase separation (LLPS), which is critical for their function to regulate Wnt/β‐catenin signaling. Here, we discuss (...) the possible roles of LLPS in Wnt/β‐catenin signaling and regulation of Axin LLPS by post‐translational modifications. (shrink)

Traditional Qiang culture is the sum of all civilizations created by Qiang people in the long historical development of the national minority, and is an important component of Chinese civilization. However, traditional Qiang culture suffered from the attack of the great 5.12 Wenchuan Earthquake in the more and more vigorous process of industralization and globalization nowadays. Based on difficulties and problems encountered in post-disaster reconstruction for cultural preservation and development, this article takes into an overall consideration of Qiang traditional cultural (...) preservation and post-disaster reconstruction, protection of nonphysical cultural heritage and national cultural resources, tries to explore the principle, approach and method of traditional Qiang cultural preservation and development and attempts to present the current situation and analyze problems, and accordingly puts forward some countermeasures, measures and specific projects with the features of scientificalness, maneuverability and development.

This paper aims to defend the use of the notion of experimental individuation, which has recently been developed by Ruey-Lin Chen, as a criterion for the reality of theoretical entities. In short, when scientists experimentally individuate an entity, a realist conclusion about that entity is warranted. We embed this claim regarding experimental individuation within a framework that allows for other criteria of reality. And we understand so-called retail arguments regarding the reality of a particular theoretical entity as arguments that (...) concern choosing an appropriate criterion of reality for that entity and determining whether the relevant first-order scientific evidence satisfies that criterion. We argue that such retail arguments are philosophical because defending criteria of reality, and showing that they are or are not satisfied in particular cases, involves work that is distinctively philosophical. And we illustrate this philosophical work by applying our criterion of experimental individuation to three historical cases: Davy’s potassium, Lavoisier’s muriatic radical, and Thomson’s electrified particles.

In recent years, while extensive researches on various networks properties have been proposed and accomplished, little has been proposed and done on network robustness and node vulnerability assessment under cascades in directed large-scale online community networks. In essential, an online directed social network is a group-centered and information spread-dominated online platform which is very different from the traditional undirected social network. Some further research studies have indicated that the online social network has high robustness to random removals of nodes but (...) fails to the intentional attacks, particularly to those attacks based on node betweenness or node directed coefficient. To explore on the robustness of directed social network, in this article, we have proposed two novel node centralities of ITG and I M p v. These two new centrality models are designed to capture this cascading effect in directed online social networks. Furthermore, we also propose a new and highly efficient computing method based on iterations for I M p v. Then, with the abundant experiments on the synthetic signed network and real-life networks derived from directed online social media and directed human mobile phone calling network, it has been proved that our ITG and I M p v based on directed social network robustness and node vulnerability assessment method is more accurate, efficient, and faster than several traditional centrality methods such as degree and betweenness. And we also have proposed the solid reasoning and proof process of iteration times k in computation of I M p v. To the best knowledge of us, our research has drawn some new light on the leading edge of robustness on the directed social network. (shrink)

Replication protein A (RPA) is the main eukaryotic single‐stranded DNA (ssDNA) binding protein, having essential roles in all DNA metabolic reactions involving ssDNA. RPA binds ssDNA with high affinity, thereby preventing the formation of secondary structures and protecting ssDNA from the action of nucleases, and directly interacts with other DNA processing proteins. Here, we discuss recent results supporting the idea that one function of RPA is to prevent annealing between short repeats that can lead to chromosome rearrangements by microhomology‐mediated end (...) joining or the formation of hairpin structures that are substrates for structure‐selective nucleases. We suggest that replication fork catastrophe caused by depletion of RPA could result from cleavage of secondary structures by nucleases, and that failure to cleave hairpin structures formed at DNA ends could lead to gene amplification. These studies highlight the important role RPA plays in maintaining genome integrity. (shrink)

Teacher education students, as an important reserve in the field of education, their growth and development are related to the future of science, economy, sustainable development of education. Through participation in the educational practice of STEAM, which integrates science, technology, engineering, art, and mathematics is more beneficial for them to acquire 21st century skills like communication, collaboration, learning innovation and critical thinking. However, little has been seen about the use and effectiveness of short videos in STEAM education activities and how (...) they can be used to support and promote teacher education students STEAM learning performance and sustainable inquiry behaviors. Therefore, this study combines the framework of triadic reciprocity determinism theory and technology acceptance theory to propose six research hypotheses and develop a research model to explore the relationship between collaborative self-efficacy, perceived usefulness of short videos, perceived ease of use, STEAM learning performance and teacher education students’ sustainable inquiry behavior. To achieve the purpose of this study, this study used purposive sampling and invited teacher education students from five classes of preschool education at a university in Guangxi Zhuang Autonomous Region, China, to participate in this study. A total of 8 h of instructional guidance was provided over a four-week period, in which participants used short videos for collaborative group learning and independent inquiry and applied STEAM concepts to kindergarten science activities. Participants’ STEAM performance was measured and surveyed during the fourth week. The results of the study validation showed that teacher education students CS-E had a positive effect on the PU and PEOU of short videos; Teacher’s education students PEOU of short videos had a positive effect on usefulness; Teacher’s education students PU and PEOU of short videos had a positive effect on STEAM learning performance; Teacher’s education students’ STEAM learning performance had a positive effect on sustainable inquiry behavior.

The long-running discourse on respect for human dignity and autonomy in the physician-patient relationship pertaining to persons with dementia (PwDs) is explored deeply in this paper through the use of a real-life case, to highlight the complex interplay between autonomy and best interest when it comes to a PwD's experiential and critical interests. Many scenarios and perspectives are described and applies to the case. However, there are a few perspectives, which are touched upon that could do with further scrutiny. Firstly, (...) it has been argued that rigid adherence to the advance directives of PwDs means that PwDs will be the only people who are not allowed to ever change their minds. This withdrawal of a fundamental freedom hardly accords with respect for human dignity, or for any residual autonomy that these individuals may still enjoy. Secondly, viewing this case through the lens of care ethics, and incorporating the recently proposed conceptual framework of anthropological vulnerability, may reveal valuable insights regarding care provision and caring physician-patient relationships. These perspectives would analyse the role of relational ontology, particularly in relation to significant others, significant communities, and caregivers. (shrink)

In this final lecture, I used instructions coming from the outside as well as rhetorical philosophy up to the achievements of the United States in the way, cited the following as high as 20 U.S. I think that the achievements in philosophy, this 20 achievements are as follows: 1. Re- definition of hermeneutics, resulting in a "philosophical hermeneutics" . understand the concern of the moment rather than the ability to explain the object. 3 allows us to explain thus an awareness (...) event. 4 to become a historical understanding of events . 5 from the hermeneutic methodology In order to understand the events into ontology. 6 to understand a sight change and self-understanding of the event. 7 principles of change as history, literature and art. 8 offers a new aesthetic and poetics. 9 provides a way to deal with representational and abstract art of art. 10 and then regardless of the art real management problem. 11 reaffirmed the non-scientific literature and hermeneutics in true sense. 12 In order to read the classical works of the original to provide a new treatment. 13 new associate with the traditional relationship. 14 the art of interpretation be linked to a reading process. 15 In order to have affected the critical nursing science, history, sociology, etc. methods. 16 criticism of the limitations of the natural scientific thinking. 17 critique of modernity . 18 provides a large amount of pull on the Park map , Hegel and Heidegger books. 19 He described the dialogue by way of consultations In order to understand the contribution. 20. Tree up hermeneutics of tradition and openness to other cultures of the ancient model. With this eight p.m. description of achievements, but also showing a structure of these nine days the future of speech. In this final lecture I take an approach from the outside and ask what Gadamer has achieved in philosophy, then list twenty of what I see as his philosophical accomplishments. These achievements are as follows: 1. Redefines hermeneutics, creating a "philosophical hermeneutics." 2. Focuses on the moment of uptake instead of the object of interpretation. 3. Makes us aware of interpretation as an event. 4. Makes the event of understanding an historical event. 5. Changes hermeneutics from a methodology to an ontology of the event of understanding. 6. Makes understanding an event of transformation of horizon and self-understanding. 7. Transforms history, literature and art as disciplines. 8. Offers a new aesthetics and a new poetics. 9. Offers a view of art that is able to deal with representation and nonrepresentational art. 10. Reintroduces the question of truth in art. 11. Revalidates literature and humanities as true in a nonscientific sense. 12. Offers a new rationale for reading the classics. 13. Forges a new relationship to tradition . 14. Relates interpretation of art to the reading process. 15. Offers a critique of method that has influenced nursing, history, sociology, etc. 16. Offers a critique of the limits of scientific thinking. 17. Offers a critique of modernity. 18. Offers major books on Plato, Hegel, and Heidegger. 19. In describing dialogue in understanding, he contributes to understanding negotiation. 20. Sets an example of hermeneutical openness to tradition, antiquity, and other cultures. The framework of these lectures during these nine day is presented through accounting for the twenty achievements. (shrink)

Academic discourses regarding teacher motivation have been on-going for decades for those who teach in ethnic minority areas. Yet research findings failed to provide a consistent conclusion regarding if kindergarten teachers’ motivation pattern would vary based on a case-to-case scenario. Therefore, further studies are needed to probe the motivation patterns among this population. The study firstly examined kindergarten teachers’ motivational profiles based on Expectancy Value Theory, and then examined how teachers’ motivation related to outcome variables. Participants included 1,199 kindergarten teachers (...) from ethnic minority areas in China. Latent profile analysis identified three motivation profiles for teachers: low value-high cost, moderate all, and high value-low cost. Teacher with different motivation profiles had significant differences in work engagement, workplace wellbeing, and retention intention. In addition, chain mediation analysis revealed that work engagement and workplace wellbeing mediated the relationship between motivation profiles and retention intention. The implications of the findings for study are discussed. (shrink)

Due in large part to the trends towards economic globalization, English has become the most widely disseminated and ubiquitous international language. The purpose of the study was to investigate what Taiwan?s EFL teachers at the elementary level believe about the policy of English as a compulsory subject and how they perceive the benefits and obstacles of the policy?s implementation. Ten elementary English teachers in Tainan City and its suburban areas participated in this study. Data were collected through teachers? interviews, classroom (...) observation and document analysis. Results found that all ten teachers agreed with the policy for English as a compulsory subject at the elementary level. They observed both positive and negative sides of this top?down policy. Classroom observation and interview data revealed that EFL teachers had to plan their English classes with the constraints on a large class of students with mixed levels of proficiency, limited teaching hours and resources. Parents? expectations of and attitudes towards English learning also became an obstacle. (shrink)

New energy vehicle policies have greatly promoted the growth of the NEV industry in China, while also attracting a lot of investor attention. Using Chinese NEV concept stocks and related industrial policies, including purchase tax incentives and promotion and application policies, issued from 2011 to 2020 as the research setting, this paper adopts a panel data model to examine the impact of policy announcement on the volatility of NEV concept stocks, as well as the mediating role of investor attention in (...) transmitting the impact. We find that NEV P&A policies have a significant and positive impact on NEV concept stock volatility, while PTI policies do not have a significant impact. Moreover, investor attention plays a partial mediating role in transmitting the impact of P&A policies on NEV stock market by increasing the stock volatility risk. Furthermore, there is heterogeneous effect of equity ownership in the relationship between policy announcement and investor attention on the volatility of NEV concept stocks; non-state-owned firms are more sensitive to the NEV P&A policies than state-owned firms. By analyzing the relationship between policy announcement and concept stock volatility, this paper enriches the research on NEV concept stocks and provides policy implications for the NEV industry.
