We investigate how firms adjust corporate pension plans in response to economic policy uncertainty (EPU). Using a sample of US-listed firms, we find that firms increase pension underfunding levels when facing higher EPU. The result is robust to controlling for pension portfolio returns, discount rates, plan sizes, pension liability, numbers of employees, other macroeconomic factors, difference-in-differences and instrumental variable estimation, and additional evidence of pension risk-shifting. Further analysis reveals that financial distress and information asymmetry induced through EPU are the potential (...) channels. The effect is stronger for firms having CEOs being excessively paid, using cash flow as a performance metric in CEO compensation, paying high dividends, and having short-term institutional investors, whereas the presence of unions, positive corporate culture, and social capital alleviate the effect. Notably, managers, not shareholders, appear to be the party reaping the benefits. Our findings suggest that firms may shift risk to employees in response to heightened uncertainty and institutional characteristics play a moderating role in this crucial business ethics issue.

End-of-life decision making frequently occurs in the intensive care unit (ICU). There is a lack of information on how a do-not-resuscitate (DNR) order affects treatments received by critically ill patients in ICUs. The objectives of this study were: (1) to compare the use of life support therapies between patients with a DNR order and those without; (2) to examine life support therapies prior to and after the issuance of a DNR order; and (3) to determine the clinical factors that influence (...) the initiation of a DNR order in ICUs in Taiwan. A prospective, descriptive, and correlational study was conducted. A total of 202 patients comprising 133 (65.8%) who had a DNR order, and 69 (34.1%) who did not, participated in this study. In the last 48 hours of their lives, patients who had a DNR order were less likely to receive life support therapies than those who did not have a DNR order. Older age, being unmarried, the presence of an adult child as a surrogate decision maker, a perceived inability to survive ultimate discharge from the ICU, and longer hospitalization in the ICU were significant predictors of issuing a DNR order for critically ill patients. This study will draw attention to how, when, and by whom, critically ill patients’ preferences about DNR are elicited and honored. (shrink)

This paper is concerned with the outer exponential synchronization of the drive-response complex dynamical networks subject to time-varying delays. The dynamics of nodes is complex valued, the interactions among of the nodes are directed, and the two coupling matrices in the drive system and the response system are also different. The intermittent pinning control is proposed to achieve outer exponential synchronization in the aperiodical way. Some novel sufficient conditions are derived to guarantee outer exponential synchronization of the considered complex-valued complex (...) networks by using the Lyapunov functional method. Finally, two numerical examples are presented to illustrate the effectiveness of the proposed control protocols. (shrink)

People's desire not to limit the meaning of Hancang driving force, continuous development and self-transcendence, which is people from within and beyond the root driving force. The so-called "inner beyond" is not a process of idealism, which began with the desire, from the bottom of the body, and go up on the layer by layer through the heart of the development process裡and mental flexibility, and would therefore have to enhance and transform. We regard the body as I desire the presence (...) of mode. Significance by the driving force in the body and thus close to the appearance, at first non-verbal, and then eventually completed in the language of representation. Through a variety of different non-linguistic representation, the meaning of the body of the driving force to obtain specific and differentiation, as music, art, dance, drama art form ... ... and so on. These different forms of art of common origins, is made ​​to understand the forms of physical exercise, as they are each other's differences, then is made ​​to understand the form of different, such as voice, image, attitude ... ... and so the nature and rules lawyers, and the rise because of their differences on the artistic and cultural expressions of different, and even the formation of the various arts precinct. In order to film art integrated voice, image and body movement, presented at the time of the current moving image, to the above description of the story. Different types of art is "the desire of the induced mover", which provides clear instructions and guidance In order to man the desire for meaning. The meaning of desire is the driving force of development of art in different fields to cross-border basic driving force. Story has entered into a description of the classification of the appearance of language, its basic features is metaphorical. Cross-disciplinary domain of the past will pin their hopes on the concepts and logical reasoning and arguments permit. Today, the language of metaphor for understanding the nature, making metaphor and narrative clues as cross-domain, and in the humanities, social sciences, natural sciences and even among. The reason why life events, actions and circumstances can be constructed to the story, because there I am with the interaction between multiple otherness, its impetus came from one continuous extrapolation, and extrapolation of each other. And diversity of his stories were always the people the story, and always coming to the multivariate description of those who hear him. Through stories, we witness In order to the meaning of life, but always to witness the way metaphor and description of each story to each other through mutual enrichment. Description of the future, after all, the story, no matter real or imagined, there is established based on the relationship regardless of which I was with him who have the freedom in the relationship, a relationship in freedom. It is also across the world who can not break the fundamental driving force and field-based. This paper assumes that there is an undetermined dynamic energy for meaningfulness in human desire, which develops and transcends any particular realization. This is the original energy by which human beings could attain transcendence by way of immanence, which is not an idealist process, but rather originated from a body-based desire that develops upwards and fuller to integrate the mental and the spiritual. Representability, first non-linguistic and then linguistic, is the access to meaning for our desire that takes body as its mode of existence. Through different forms of representation, such as sounds, pictures and gestures ... etc., the project of meaning is specified. The movement of body in intelligible forms is the common origin of music, dancing and performative arts. Cultural difference and artistic boundaries are based upon differences in the nature and rule of these intelligible forms. The art of filming, which synthesizes image, music and body movement in presenting images moving in time so as to tell stories of various kinds. All forms of art are "inducers of desire" by articulating, determining and guiding our desire for meaning. This dynamic development of our desire for meaning is the common basic energy by which we can cross the borders of different arts. Story-telling presupposes linguistic representation accessible to our meaning dynamism. In the past, concepts and logical reasoning and argumentation were taken to be the hope for interdisciplinary research. But now, with the better understanding we have of the metaphoric nature of language, metaphors and narratives are taken to be the clue for a cross-bordering effort in different sciences, human , social and natural. If there are events, actions and plots in human existence to be constructed as stories, it is because there is always interaction with multiple others, the dynamism of it consisting in our incessant act of strangification and mutual strangification. Stories are always stories about one self with multiple others and told to multiple others. By telling stories, we witness a particular way of meaningful life, always metaphorically interpreted. We achieve mutual enrichment by telling stories to each other. The ultimate foundation of cross-bordering in arts and scientific disciplines consists in the ontology of dynamic relation, in which there is relatedness in freedom and freedom in being related, and this is the ground on which all our life stories, both real and imaginative, are based.

BackgroundPlagiarism is common and threatens the integrity of the scientific literature. However, its detection is time consuming and difficult, presenting challenges to editors and publishers who are entrusted with ensuring the integrity of published literature.MethodsIn this study, the extent of plagiarism in manuscripts submitted to a major specialty medical journal was documented. We manually curated submitted manuscripts and deemed an article contained plagiarism if one sentence had 80 % of the words copied from another published paper. Commercial plagiarism detection software (...) was utilized and its use was optimized.ResultsIn 400 consecutively submitted manuscripts, 17 % of submissions contained unacceptable levels of plagiarized material with 82 % of plagiarized manuscripts submitted from countries where English was not an official language. Using the most commonly employed commercial plagiarism detection software, sensitivity and specificity were studied with regard to the generated plagiarism score. The cutoff score maximizing both sensitivity and specificity was 15 % (sensitivity 84.8 % and specificity 80.5 %).ConclusionsPlagiarism was a common occurrence among manuscripts submitted for publication to a major American specialty medical journal and most manuscripts with plagiarized material were submitted from countries in which English was not an official language. The use of commercial plagiarism detection software can be optimized by selecting a cutoff score that reflects desired sensitivity and specificity. (shrink)

Some of the authors of the essays on Chinese philosophers prefer the pin yin system of romanization for Chinese names and words, while others prefer the Wade‐Giles system. Given that both systems are in wide use today, important names and words are given in both their pin yin and Wade‐Giles formulations. The author's preference is printed first, followed by the alternative romanization within brackets.

Objectives: Neuroplastic changes that drive recovery of shoulder/elbow function after stroke have been poorly understood. The purpose of this study was to determine the relationship between neuroplastic brain changes related to shoulder/elbow movement control in response to treatment and recovery of arm motor function in chronic stroke survivors.Methods: Twenty-three chronic stroke survivors were treated with 12 weeks of arm rehabilitation. Outcome measures included functional Magnetic Resonance Imaging (fMRI) for the shoulder/elbow components of reach and a skilled motor function test (Arm (...) Motor Abilities Test, AMAT), collected before and after treatment.Results: We observed two patterns of neuroplastic changes that were associated with gains in motor function: decreased or increased task-related brain activation. Those with significantly better motor function at baseline exhibited a decrease in brain activation in response to treatment, evident in the ipsilesional primary motor and contralesional supplementary motor regions; in contrast, those with greater baseline motor impairment, exhibited increased brain activation in response to treatment. There was a linear relationship between greater functional gain (AMAT) and increased activation in bilateral primary motor, contralesional primary and secondary sensory regions, and contralesional lateral premotor area, after adjusting for baseline AMAT, age, and time since stroke.Conclusions: Recovery of functional reach involves recruitment of several contralesional and bilateral primary motor regions. In response to intensive therapy, the direction of functional brain change (i.e., increase or decrease in task-related brain recruitment) for shoulder/elbow reach components depends on baseline level of motor function and may represent either different phases of recovery or different patterns of neuroplasticity that drive functional recovery.

Compare with other professions, teachers are reported to have a higher risk of poor mental health. This study examined the relationships between emotional intelligence, perceived organizational justice, and mental health among Chinese high school teachers. Three hundred and eighty-one high school teachers, with their age range between 21 and 50 years, were administered the Emotional Intelligence Scale, Perceived Organizational Justice Scale, and Mental Health Scale. The result found that emotional intelligence and perceived organizational justice directly influence the mental health of (...) high school teachers. In addition, perceived organizational justice mediated the association between emotional intelligence and mental health. Moreover, the present study analyzes the different role of subtypes of perceived organizational justice on the relationships between emotional intelligence and mental health, and the results showed that the mediating effects of perceived distributive justice and interactive justice on emotional intelligence and mental health are not significant, only the perceived procedural justice mediated the relationships between emotional intelligence and teachers’ mental health. The results are discussed in a conceptual context. (shrink)

In recent years, learning materials have gradually been applied to flipped classrooms. Teachers share learning materials, and students can preview the learning materials before class. During class, the teacher can discuss students' questions from their notes from previewing the learning materials. The social media platform Facebook provides access to learning materials and diversified interactions, such as sharing knowledge, annotating learning materials, and establishing common objectives. Previous studies have explored the effect of flipped classrooms on students' learning engagement, attitudes, and performance. (...) In this paper, we apply educational data mining to explore the relationship between students' viewing behaviors in accessing learning materials and their performance in flipped classrooms. The participants are classified into an experimental group and a control group to engage in flipped classroom activities. The experimental group uses the social media platform Facebook for flipped learning, and the control group uses a learning management system for flipped learning. The results show that there is a significant difference in the learning performance between the two groups, with the average score of the experimental group being higher than that of the control group. Furthermore, we find that the viewing behaviors and performance of the students within the experimental group differ significantly. (shrink)

Digitized information and network have made an enormous impact on the music and movie industries. Internet piracy is popular and has greatly threatened the companies in these industries. This study tests Hunt-Vitell’s ethical decision model and attempts to understand why and how people share unauthorized music files with others in the peer-to-peer (P2P) network. The norm of anti-piracy, the ideology of free software, the norm of reciprocity, and the ideology of consumer rights are proposed as four deontological norms related to (...) using P2P systems. The model is tested using a scenario survey with four alternatives; the results indicate that the deontological norm of anti-piracy is not a main factor in affecting P2P users’ ethical considerations regarding sharing files with others. This finding suggests that to protect their property rights, record companies should try to realize the consumer benefits brought via new digital and network technology, instead of simply declaring their intellectual property and resisting the innovations resulting from new technologies.

In this study, we tested a possible mechanism of the association between math anxiety and math achievement: the mediating role of math-specific grit. In Study 1, a sample of 10th grade students completed a battery of personality and attitude questionnaires, and math achievement was indexed by curriculum-based examination scores. Mediation analyses indicated that math-specific grit, but not domain-general grit, mediated the relationship between math anxiety and math achievement. In Study 2, we replicated and extended the above findings with another sample (...) of 11th grade students. Mediation analyses indicated that math-specific grit and math-specific procrastination played sequential mediating roles in the relationship between math anxiety and math achievement. That is, individuals with higher math anxiety were less gritty in math learning, possibly further leading them to be more procrastinated in performing math work, which may finally result in worse math achievement. In summary, the current study provides the first evidence that math-specific grit may mediate the relationship between math anxiety and math achievement. Furthermore, it also demonstrated the value of math-specific grit over domain-general grit in predicting math success, which invites a broader investigation on subject-specific grit. (shrink)

Neuroscience communication is increasingly taking place on multidirectional social media platforms, creating new opportunities but also calling for critical ethical considerations. Twitter, one of the most popular social media applications in the world, is a leading platform for the dissemination of all information types, including emerging areas of neuroscience such as optogenetics, a technique aimed at the control of specific neurons. Since its discovery in 2005, optogenetics has been featured in the public eye and discussed extensively on social media, but (...) little is known about how this new technique is portrayed and who the users participating in the conversation are. To address this gap, we conducted content analysis of a sample of 1000 tweets mentioning “optogenetics” over a one-year period between 2014 and 2015. We found that academic researchers are the largest group contributing to the conversation, that the tweets often contain links to third-party websites from news organizations and peer-reviewed journals, and that common thematic motifs include the applications of optogenetics specifically for the control of brain activity and the treatment of disease. We also found that the majority of the tweets are neutral in their tone regarding optogenetics. As Twitter serves as a current and dynamic forum for exchange about advances in neuroscience, the conversation about optogenetics on this engaging platform can inform socially-responsive knowledge dissemination efforts in this area.

Previous research has explored how emotional valence affected face-context associative memory, while little is known about how arousing stimuli that share the same valence but differ in emotionality are bound together and retained in memory. In this study, we manipulated the emotional similarity between the target face and the face associated with the context emotion, and examined the effect of emotional similarity of negative emotion on face-context associative memory. Our results showed that the greater the emotional similarity between the faces, (...) the better the face memory and face-context associative memory were. These findings suggest that the processing of facial expression and its associated context may benefit from taking into account the emotional similarity between the faces. (shrink)

Background: To evaluate the effectiveness of a multifaceted intervention in improving emergency department (ED) patient privacy and satisfaction in the crowded ED setting. Methods: A pre- and post-intervention study was conducted. A multifaceted intervention was implemented in a university-affiliated hospital ED. The intervention developed strategies to improve ED patient privacy and satisfaction, including redesigning the ED environment, process management, access control, and staff education and training, and encouraging ethics consultation. The effectiveness of the intervention was evaluated using patient surveys. Eligibility (...) data were collected after the intervention and compared to data collected before the intervention. Differences in patient satisfaction and patient perception of privacy were adjusted for predefined covariates using multivariable ordinal logistic regression. Results: Structured questionnaires were collected with 313 ED patients before the intervention and 341 ED patients after the intervention. There were no important covariate differences, except for treatment area, between the two groups. Significant improvements were observed in patient perception of "personal information overheard by others", being "seen by irrelevant persons", having "unintentionally heard inappropriate conversations from healthcare providers", and experiencing "providers' respect for my privacy". There was significant improvement in patient overall perception of privacy and satisfaction. There were statistically significant correlations between the intervention and patient overall perception of privacy and satisfaction on multivariable analysis. Conclusions: Significant improvements were achieved with an intervention. Patients perceived significantly more privacy and satisfaction in ED care after the intervention. We believe that these improvements were the result of major philosophical, administrative, and operational changes aimed at respecting both patient privacy and satisfaction. (shrink)

Customer bullying is a common phenomenon, causing short-term emotional distress or having long-term psychological impact on frontline employees of service enterprises, yielding either direct or indirect losses to service enterprises. While existing research has focused on the emotional and psychological impact of customer bullying on employees, little attention has been directed at the impact of customer bullying on negative employee behavior and internal mechanisms. In view of this, this paper draws on conservation of resources theory and discusses how and when (...) customer bullying can lead to unethical behaviors. Furthermore, the mediating role of job insecurity and the moderating effect of organizational identification are analyzed. In study 1, 181 valid questionnaire data were collected at two time points, and regression data analysis was used to explore the effect of customer bullying on unethical behaviors through job insecurity. In study 2, 212 employees were recruited to investigate the moderating effect of organizational identification between customer bullying and unethical behaviors through a scenario experimental study. The results reveal that customer bullying is positively related to employees’ job insecurity and unethical behaviors. Job insecurity partially mediates the positive relationship between customer bullying and unethical behaviors. Further, the regression analysis results indicate that the direct effect of customer bullying on unethical behaviors is moderated by organizational identification. This study provides theoretical guidance for entrepreneurs to reduce both employee job insecurity and unethical behavior. (shrink)

For International Relations scholars, discussions of globalization inevitably turn to questions of sovereignty. How much control does a country have over its borders, people and economy? Where does that authority come from? _Sovereign Lives_ explores these changes through reading of humanitarian intervention, human rights discourses, securitization, refugees, the fragmentation of identities and the practices of development.

Resumo: A música tradicional chinesa tem uma longa história, repleta de conceitos estéticos ricos e extensos. A integração da música tradicional e das ideias estéticas tem um impacto significativo na formação do sistema musical tradicional da China. Este artigo explora a influência interativa da música tradicional e das ideias estéticas, analisando as ideias musicais da estética tradicional chinesa, buscando promover a integração e o desenvolvimento da música tradicional e das ideias estéticas. Discute o conteúdo das ideias estéticas musicais do confucionismo, (...) taoísmo e moísmo, bem como a posição das ideias estéticas na música tradicional chinesa. Ao combinar e analisar a literatura relevante, livros antigos e materiais históricos, é possível compreender a evolução histórica e a influência mútua da música tradicional e do pensamento estético. Os conceitos estéticos tradicionais não só desempenharam um papel importante no desenvolvimento da música chinesa, mas também na promoção do desenvolvimento da música chinesa, ao longo de milhares de anos de história. Na avaliação da interação entre a música tradicional e o pensamento estético, pode ocorrer uma situação em que o conceito seja demasiado simplificado. A relação entre a música tradicional e o pensamento estético é muito complicada, envolvendo muitas escolas, períodos históricos e regiões. Pode não ser capaz de cobrir totalmente todos os fatores de influência, se for resumido apenas pelo confucionismo, taoísmo e budismo. Sugere-se que a educação e a herança da música tradicional e das ideias estéticas sejam fortalecidas, na educação musical. Artistas musicais mais tradicionais e os teóricos da estética devem ser cultivados, a fim de poder transmitir a música tradicional e as ideias estéticas às gerações futuras e continuar a desenvolver-se e a inovar, na sociedade contemporânea.

With the increasing proportion of the logistics industry in the economy, the study of the vehicle routing problem has practical significance for economic development. Based on the vehicle routing problem, the customer presence probability data are introduced as an uncertain random parameter, and the VRP model of uncertain customers is established. By optimizing the robust uncertainty model, combined with a data-driven kernel density estimation method, the distribution feature set of historical data samples can then be fitted, and finally, a distributed (...) robust vehicle routing model for uncertain customers is established. The Q-learning algorithm in reinforcement learning is introduced into the high-level selection strategy using the hyper-heuristic algorithm, and a hyper-heuristic algorithm based on the Q-learning algorithm is designed to solve the problem. Compared with the certain method, the distributed robust model can effectively reduce the total cost and the robust conservatism while ensuring customer satisfaction. The improved algorithm also has good performance. (shrink)

ObjectiveThis study used a moderated mediation model to test the mediating effect of anxiety on the relationship between negative perfectionism and sleep quality and the moderating effect of COVID-19 epidemic risk perception during the COVID-19 pandemic in Chinese international students.Materials and methodsA sample of 239 Chinese international students from the south of China, was surveyed with the Negative and Positive Perfectionism Scale, the Pittsburgh Sleep Quality Index, the General Anxiety Disorder Scale, and the COVID-19 Epidemic Risk Perception Inventory. Version 23.0 (...) of SPSS and version 3.4 of PROCESS were used to perform the correlation analyses, mediation analysis, and moderated mediation analysis.Results Negative perfectionism was significantly correlated with anxiety and poor sleep quality. Anxiety was significantly correlated with poor sleep quality. The mediating effect test showed that anxiety had a mediating effect between negative perfectionism and poor sleep quality. Epidemic risk perception moderated the mediating effect of anxiety between negative perfectionism and poor sleep quality.ConclusionNegative perfectionism affected sleep quality indirectly through anxiety. In particular, COVID-19 epidemic risk perception moderated the relationship between anxiety and sleep quality, such that the association was stronger when the COVID-19 epidemic risk perception was high. These results provide a more comprehensive understanding of the negative link between negative perfectionism and poor sleep quality. (shrink)
