Ensuring adequate informed consent for surgery in a trauma setting is challenging. We developed and pilot tested an educational video containing information regarding the informed consent process for surgery in trauma patients and a knowledge measure instrument and evaluated whether the audiovisual presentation improved the patients’ knowledge regarding their procedure and aftercare and their satisfaction with the informed consent process. A modified Delphi technique in which a panel of experts participated in successive rounds of shared scoring of items to forecast (...) outcomes was applied to reach a consensus among the experts. The resulting consensus was used to develop the video content and questions for measuring the understanding of the informed consent for debridement surgery in limb trauma patients. The expert panel included experienced patients. The participants in this pilot study were enrolled as a convenience sample of adult trauma patients scheduled to receive surgery. The modified Delphi technique comprised three rounds over a 4-month period. The items given higher scores by the experts in several categories were chosen for the subsequent rounds until consensus was reached. The experts reached a consensus on each item after the three-round process. The final knowledge measure comprising 10 questions was developed and validated. Thirty eligible trauma patients presenting to the Emergency Department were approached and completed the questionnaires in this pilot study. The participants exhibited significantly higher mean knowledge and satisfaction scores after watching the educational video than before watching the video. Our process is promising for developing procedure-specific informed consent and audiovisual aids in medical and surgical specialties. The educational video was developed using a scientific method that integrated the opinions of different stakeholders, particularly patients. This video is a useful tool for improving the knowledge and satisfaction of trauma patients in the ED. The modified Delphi technique is an effective method for collecting experts’ opinions and reaching a consensus on the content of educational materials for informed consent. Institutions should prioritize patient-centered health care and develop a structured informed consent process to improve the quality of care. The ClinicalTrials.gov Identifier is NCT01338480.

We investigated whether, in the emergency department, educational video-assisted informed consent is superior to the conventional consent process, to inform trauma patients undergoing surgery about the procedure, benefits, risks, alternatives, and postoperative care. We conducted a prospective randomized controlled trial, with superiority study design. All trauma patients scheduled to receive trauma-related debridement surgery in the ED of Kaohsiung Medical University Hospital were included. Patients were assigned to one of two education protocols. Participants in the intervention group watched an educational video (...) illustrating informed consent information, whereas those in the control group read an informed consent document. The primary outcome was knowledge scores and the secondary outcome was assessment of patient satisfaction. A multivariable regression model, with predefined covariates, was used to analyze differences in knowledge scores and patient satisfaction levels between the groups. A total of 142 patients were enrolled, with 70 and 72 assigned to the intervention and control groups, respectively. Mean knowledge scores were higher in the intervention ) than in the control group. By multivariate analysis, the intervention group had significantly greater differences in knowledge scores. Age, injury severity score, and baseline knowledge score significantly affected the differences in knowledge scores. Significant improvements were observed in patients’ perception of statements addressing comprehension of the information provided, helpfulness of the supplied information for decision making, and satisfaction with the informed consent process. Multivariate analysis showed significant correlations between video education and patient satisfaction. Both the educational approach and severity of injury may have an impact on patient understanding during the informed consent process in an emergency environment. Video-assisted informed consent may improve the understanding of surgery and satisfaction with the informed consent process for trauma patients in the ED. Institutions should develop structured methods and other strategies to better inform trauma patients, facilitate treatment decisions, and improve patient satisfaction.

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)

Healthcare workers’ voice is of importance in decreasing medical accidents and improving the efficacy of hospital units. To investigate the impact and the underlying mechanisms of supervisors’ negative mood on healthcare workers’ voice behavior, based on the mood contagion perspective, we designed a cross-sectional study, with 299 healthcare workers from mainland China completed the questionnaires. The results indicated supervisors’ negative mood was positively related to healthcare workers’ negative mood, which further led to less constructive voice and more defensive voice. Moreover, (...) the healthcare worker’s emotional intelligence aspect of self-emotion appraisal moderated this relationship, but not others-emotion appraisal. We believe healthcare workers’ supervisors should pay attention to their negative mood expression and regulation. In the hope of reducing being influenced by supervisors’ negative mood, training about noticing and recognizing their own emotions are needed for healthcare workers. (shrink)

Due to the development of information technology, music piracy has become an escalating problem. This study attempts to employ the theory of planned behavior (TPB) and the social identity theory to investigate the antecedents of downloading pop music illegally from the Internet, the relationship between the intention to illegally download music and the intention to buy music, and the moderating effects of idolatry. Data were collected from 350 teenagers in Northern Taiwan through questionnaire interviews conducted in city centers where teenagers (...) gather. The results of partial least squares (PLS) analyses reconfirm the explanatory power of the TPB model with regard to the pop music illegal downloading behavior. However, it is interesting to note that the intention to illegally download music does not have a significant influence on the intention to buy music. This finding contradicts our common intuitions. Further analyses also reveal that idolatry moderates the relationship between the intention to illegally download music and the intention to buy music. For teenagers with high idolatry, a higher music downloading intention results in a lower buying intention. One possible explanation is the price of music CDs. Several interviews were also held to verify our results. Implications and a discussion are then provided. (shrink)

Kripke (Wittgenstein on rules and private language: an elementary exposition. Harvard University Press, Cambridge Mass, 1982 ) rejected a naturalistic dispositional account of meaning (hereafter semantic dispositionalism) in a skeptical argument about rule-following he attributes to Wittgenstein (Philosophical investigation. Basil Blackwell, Oxford, 1958 ). Most philosophers who oppose Kripke’s criticisms of semantic dispositionalism take the stance that the argument proves too much: semantic dispositionalism is similar to much of our respected science in some important aspects, and hence to discard the (...) former would mean to give up the latter, which is obviously wrong. In this paper, I shall discuss and reject a recent defense of Kripke by Kusch (Analysis 65(2):156–163 2005 ; Sceptical guide to meaning and rules: defending Kripke’s Wittgenstein. McGill-Queen’s, London, 2006 ). Kusch attempts to show that semantic dispositionalism differs from the sciences, and consequently, Kripke’s attack can only target semantic dispositionalism, but not the sciences. Specifically, Kusch identifies some important features of the sciences with regard to how it employs idealization and ceteris paribus clauses, and argues that the ways in which semantic dispositionalism uses them are dramatically different. I argue that, upon close examination, the two are more similar than otherwise in each of those features. (shrink)

Research on ethical leadership in organizations has been largely based on Western philosophical traditions and has tended to focus on Western corporate experiences. Insights gained from such studies may however not be universally applicable in other cultural contexts. This paper examines the normative grounds for an alternative Confucian virtue-based ethics of leadership in China. As with Western corporations, organizational practices in China are profoundly shaped by their own cultural history and philosophical outlook. The ethical norms guiding both the practice and (...) theory of leadership in China are underpinned by indigenous Chinese wisdoms imbued in their own traditions and China’s collective psyche. Focusing on three fundamental aspects of Confucian virtue ethics: _ren_ (仁 benevolence), _yi_ (义 righteousness) and _li_(礼 ritual propriety), this paper proposes that an ideal Confucian leader regards self-cultivation as a first priority; status and material gain, whilst important, are not the foremost concern. S/he exemplifies the virtuous role model, exudes moral charisma and influences others by shaping an organization’s ethical culture through the process of ritualization. The paper concludes by claiming that amplifying the explicit discourse around Confucian virtue ethics will help contribute to the development of better ethical leadership in China. (shrink)

Anti-intellectualists claim that knowledge-how requires at least a corresponding ability or performance success that includes non-intellectual components. They argue that an insistence on the close relationship between knowledge-how and performance success is needed to account for our intuitions on the practical aspects of knowledge-how. In this paper, we examine three main anti-intellectualist proposals for what constitutes performance success, those of Hawley, Noë, and Kumar, and argue that all of them are non-informative in a practical manner. We further point out that (...) the problem of non-informativeness is dominant in anti-intellectualism. (shrink)

Handfield and Bird claim that dispositionalists such as Martin and Heil appeal to antidotes and finks to explain why and how a conditional analysis of dispositions falls to Kripke's criticisms, but fail. The main reason is that some antidotes and finks are unavoidably intrinsic and relatively permanent in an agent, in which case the ascription of a rule-following disposition to the agent is false. In this paper, I contend that the presence of intrinsic and relatively permanent finks or antidotes does (...) not imply the absence of a rule-following disposition; some additional condition is needed for this implication to go through, but remains wanting. I end the paper with a discussion of where the real challenge lies for realist dispositionalism. (shrink)

The COVID-19 pandemic has had a significant impact on education worldwide. The disease first hit China and numerous Chinese cities then started to conduct online courses. Therefore, this study aims to explore the effect of the Shanghai students’ emotional intelligence, learning motivation, and self-efficacy on their academic achievement when they participated in online English classes during the latter phase of the pandemic in China. Furthermore, the research also examines whether the students’ emotional intelligence can influence their academic achievement through the (...) mediation effect of their learning motivation and self-efficacy. Social Cognitive Theory and the social cognitive Expectancy-Value Model were employed to build the research framework, and the method of structural equation modeling was utilized to conduct the model verification. Ten universities in Shanghai, China were selected for sampling. In total, 450 students were surveyed of which 404 questionnaires were valid. The results show that the students’ emotional intelligence did not directly affect their academic achievement. Nevertheless, the students’ emotional intelligence had a positive effect on their learning motivation and self-efficacy. In addition, mediation analysis showed that the relation between emotional intelligence and academic achievement was sequentially mediated by learning motivation and self-efficacy. (shrink)

The rapid development of digital technologies has transformed the world but can be a double-edged sword. We study the interaction of important variables that affect individual news reporters’ performance in which digital technology is the dominant feature. A multilevel model illustrates how transactive memory and job competence affect individual performance. The empirical study includes data from 19 teams of news reporters and 211 valid survey responses, applying hierarchical linear modeling to analyze the data. The results indicate that transactive memory and (...) technology competence help to improve a reporter’s job performance. More importantly, teamwork competence fully mediates the relationships. Our findings thus suggest that teamwork competence is the core skill. Neither technology competence nor transactive memory alone translates directly into enhanced individual performance. (shrink)

The purpose of this paper is to look at the problem of rule-following—notably discussed by Kripke (Wittgenstein on rules and private language, 1982) and Wittgenstein (Philosophical investigations, 1953)—from the perspective of the study of generics. Generics are sentences that express generalizations that tolerate exceptions. I first suggest that meaning ascriptions be viewed as habitual sentences, which are a sub-set of generics. I then seek a proper semantic analysis for habitually construed meaning sentences. The quantificational approach is rejected, due to its (...) persistent difficulties. Instead, a cognitive approach is adopted, where psychological considerations of meaning attributors play a crucial role. This account is then compared with the picture of meaning offered by Kripke and Wittgenstein, respectively. I show how this fresh way of conceiving of meaning sentences respects some of their insights while avoiding some of the drawbacks, and serves to improve the framework in which the current debate and inquiry about rule-following are conducted.

This paper proposes extending the appearance of artefacts from human to zoomorphic on the basis of the uncanny valley phenomenon, while simultaneously realising the effects of bionic species, product realism, and gender differences on preschool children’s preferences for artificial animal appearances. In this study, animal toys were created as stimuli and a three-factor experiment was conducted with preschool children. Overall, the children demonstrated significantly stronger preferences for animal toys with extremely high or moderate realism compared with those with extremely low (...) realism. Specifically, the boys preferred the toys with extremely high realism, and the girls preferred those with moderate realism. We conclude with some suggestions regarding the direction of design guidelines for the appearance of artificial animals, to facilitate the design and creation of animal products that promote human–robot interactions and design education.

This study is based on the situation of Taiwan listed companies as derivative financial products from 2015 to 2017, analyzing the relationship between the hedging of derivative financial products and characteristics of enterprises and the factors that affect the hedging decision-making of companies. It is found that even after the announcement of Taiwan’s No. 34 and No. 36 bulletins, there are still some problems that are needed to improve in the disclosure of derivative financial product investment information by Taiwan’s listed (...) companies, at least in the disclosure of the reasons for this conduct which is still insufficient. In this study, two-stage regression analysis method is applied to empirical analysis, and it is found that hedging activities are related to corporate characteristics, such as expected financial crisis costs, corporate size, equity issues, growth investment opportunities, and information asymmetry. In the investment of derivative financial products, enterprises should evaluate their own financial characteristics as a reference for the risk avoidance decision. At the same time, it is necessary to investigate different natures of hedging tools used in appropriate risk categories, so as to fully achieve the hedging effect and maximize the hedging benefits. This study also found that companies with higher growth investment opportunities, larger size, and higher financial crisis costs will tend to use derivative financial products for hedging. As for the impact of other industries, it is found that the electronic and electrical machinery industries are more active than other industries in hedging behaviors of undertaking derivative financial products’ transaction.

Semantic analysis of contemporary philosophical inquiry is the core problem, and Quine is undoubtedly in the twentieth century conducted to explore the semantic engineering裡arduous, the most influential of modern thinkers. However, although the impact of Quine's great, he semantics regardless of the stance taken by the natural person has not yet been fully satisfied instruction understanding. On the one hand, the based on Quine's controversial idea of the uncertainty, scholars widely believe that regardless Quine's stance is a natural suspicion regardless (...) of extreme stance: the meaning of the word does not exist. On the other hand, Quine in the construction regardless of its license, but to take a natural tendency to analyze the nature of the so-called "stimulus word meaning" future language sentences as the core foundation of semantics. Thus, Quine's semantic natural stance regardless what is a semantic canceled regardless, have a language or meaning regardless of the orientation of some, not very clear. This paper has two purposes: First, the author regardless above, Quine's natural regardless stance in a number of philosophers to cancel regardless positioning, is the station does not live foot stance; Second, in the text, based on Quine's natural regardless stance can be is portrayed as some kind of weaker version of about regardless, and this stance is more feasible. The investigation of linguistic meaning has been central in contemporary analytic philosophy. Quine is undoubtedly one of the most influential thinkers in the 20 century in this daunting inquiry. Despite his enormous influence, however, Quine's naturalistic perspective on meaning has not been properly understood. On the one hand, Quine's view, presented in the controversial indeterminacy thesis, is widely taken as a radical form of skepticism, namely, meaning does not exist. On the other hand, Quine invokes and heavily relies on the notion of disposition to analyze the idea of ​​stimulus meaning, which lies at the heart of Quine's discussion of linguistic meaning. It does not seem entirely clear whether Quine attempts to eliminate meaning, or to naturalize meaning by reducing it to dispositions. The aim of this paper is argue for two points. First, construing Quine's position as semantic eliminativism, as many do, Quine's position would be in deep trouble. Second, based on a textual basis, Quine's position can be alternatively construed as a modest form of dispositional reductionism, which is more tenable. (shrink)

Global climate change arouses people’s attention to environmental protection and, therefore, changes consumption habits. Food overconsumption not only produces extra waste but also pollutes the environment. Therefore, it is important to understand the factors that motivate people to eat green, an eco-friendly way to consume food. To keep the body in good shape, the fitnessers concern more about diet than the general people. This study explored intrinsic motivations, such as social recognition, environmental ethics, curiosity, joy of purchase, perceived usefulness, subjective (...) norm, and perceived behavior control as constructs that affect fitnesser’s green eating intention. All constructs except curiosity have significant impacts on behavior intention. The results demonstrate that social recognition and environmental ethics have significant effects on curiosity, joy of purchase, perceived usefulness, subjective norm, and perceived behavior control. The mediation effects between social recognition and behavior intention are not supported. The mediators between environmental ethics and behavior intention are joy of purchase, perceived usefulness, subjective norm, and perceived behavior control. (shrink)

This paper presents an adaptive fuzzy sliding-mode controller for multiple Euler–Lagrange systems communicated with directed topology. Based on the graph theory and Lyapunov–Krasovskii functions, a delay-dependent sufficient condition for the existence of sliding surfaces is given in terms of linear matrix inequalities. The asymptotic stability is analyzed by using the Lyapunov method in the presence of unknown parametric dynamics, actuator faults, and time-varying delays. The usage of adaptive techniques is to adapt the unknown parameters so that the objective of globally (...) asymptotic stability is achieved. Finally, simulation results are provided to illustrate the effectiveness of the proposed control scheme. (shrink)

Identifying the theme of self and death as central to the “Qiwulun” — or Discussion on Making All Things Equal3 — is at odds with a majority of interpreters: they tend to see issues such as the possibility of knowledge and the nature of language or epistemic perspectives as lying at the core of the concerns for Zhuangzi. Chad Hansen, for instance, ascribes a thoroughgoing version of skepticism and relativism to Zhuangzi, a position stating that nothing can be known and (...) no school of thought enjoys a privileged status over others (Hansen 1983, 1992).

Violence has been linked to the co-occurrence of cognitive dysfunction and altered activations in several brain regions. Empirical evidence demonstrated the benefits of acute exercise on motor inhibition and error detection and their neuronal processing. However, whether such effects also hold for the population with violent behaviors remains unknown. This study examined the effects of acute aerobic exercise on inhibitory control and error monitoring among violent offenders. Fifteen male violent offenders were counterbalanced into experimental protocols, which comprised a 30-min moderately (...) aerobic exercise [60% heart rate reserve] and a 30-min reading control session. After each session, participants performed an emotional stop signal task while event-related potentials were recorded simultaneously. Results showed insignificant changes in ERPs components [i.e., N2, P3, error-related negativity, and error-positivity amplitudes] and the behavioral performance in go condition, stop accuracy, and post-error adjustments by exercise. However, the current study demonstrated that the acute exercise facilitated stop signal reaction time when compared to the control session regardless of emotional conditions. This is the first research to exhibit the improvements in inhibitory performance by acute exercise for violent offenders. Most importantly, this effect was independent of affective settings, expanding the existing knowledge of the influences of acute exercise on cognition. Our findings implicate the perspective of acute exercise for clinical and correctional practices. (shrink)

Construction schedules play an important role in construction project management. However, during construction activities, risks may arise due to unexpected schedule changes, resulting in the ineffective delivery of projects. This study aims to reveal the law of schedule change risk propagation and to analyze the effects on the risk propagation through numerical simulations. First, construction projects are represented by activity-on-node networks. A model of risk propagation is then built based on a susceptible-infected model considering the effects of the nodal characteristics (...) on the propagation process. Next, the model is tested on a real-world project to examine cascading failures with varying parameters. The experimental results demonstrate that the model is effective in identifying the activities most capable of affecting a project schedule and evaluating the impact of schedule change risk propagation. This study will provide a basis for enhancing the robustness of AON networks and controlling the propagation of schedule change risks. (shrink)

The phrase of ceteris paribus , i.e., other things being equal, is widely employed to state laws in non-basic sciences, such as economics, medicine, geography, biology, and psychology. However, what the phrase in question says is highly unclear, which results in severe philosophical problems calling into question the status of special sciences. The main purpose of this paper is to critically examine a lexicographic study of cp proposed by Michael Morreau , who tries to provide an adequate semantic analysis of (...) cp-laws through this study. It is argued that, despite Morreau’s attempt to excavate meanings possibly contained in a cp-phrase, his proposal is very limited in the progress it makes. Toward the end of this paper, an alternative approach is sketched, in which the pragmatic role played by cp in the sciences is emphasized. (shrink)

The rule-following paradox of Kripke's Wittgenstein posits that there is no fact of the matter about an individual that can determine whether he means one thing or another by a term, such as "+". The paradox thus renders the existence of meaning illusory. The objective of this thesis is to examine the paradox and try to offer a version of a dispositional account that can counteract Kripke's skeptics. ;Gaining insights from previous dispositionalist accounts of meaning and rule-following, including those of (...) Dretske, Fodor, Millikan, Martin & Heil, Shogenji, and Yallowitz, my project is to put all those insights together to formulate a functional view of human dispositions to rule-following which will resolve the error, finitude, and first-person epistemic problems that Kripke raises against the dispositionalist approach. Specifically, I argue that rule-following or meaning consists in one's possessing a disposition, realistically construed. A rule-following disposition is real in the sense that it is responsible for, and hence not to be equated with, its manifestations under various conditions. A person acquires a real disposition to rule-following through a learning history which is constrained by biologically innate human endowments of learning and cognition. The error problem then becomes the problem of how to identify the disposition without vacuity or circularity. My claim is that identifying a rule-following disposition is a task of scientific hypothesizing, which is epistemically and methodologically sound. The finitude problem is in my view a form of Humean inductive skepticism. My response to it is to adopt a reliabilist theory of justification and its treatment of the induction problem. A distinctive contribution of mine is to offer a functionalist account of dispositions and introspection in the resolution of the first-person epistemic problem. My aim is to do full justice to the phenomenology and epistemology of meaning and rule-following from the first-person point of view. ;My conclusion is that a satisfactory dispositional account such as the one I offer not only vindicates the reality of rule-following and meaning but also increases our understanding of the nature of meaning and human rule-following phenomenon.

This study investigates the effects of visual mnemonics and the methods of presenting learning materials on learning visually similar characters for Chinese-as-second-language learners. In supporting CSL learners to build robust orthographic representations in Chinese, addressing the challenges of visual similarity of characters is an important issue. Based on prior research on perceptual learning, we tested three strategies that differ in the extent to which they promote interrelated attention to the form and meaning of characters: Stroke Sequence, a form-emphasis strategy, Key-images, (...) a form + meaning strategy utilizing visual code, Pithy Formulas with Key-images, a form + meaning strategy combining visual and verbal codes. A pretest–posttest equivalent-group design was adopted. The independent variables were the learning strategy, the method of presenting character pairs, and testing time. The dependent variables were learners’ proportions of accurate responses to reading and writing Chinese characters through a posttest and a delayed posttest ; a learner experience survey was also administered to investigate learners’ opinions on each strategy. Sixty-six non-beginning learners of Chinese participated; they were randomly assigned to one of the two groups in which participants learned ten characters via the three strategies, respectively, differing between whether the characters were presented in similar pairs or dissimilar pairs. Data were analyzed via three-way ANCOVAs. The Pithy Formulas with Key-images and the Key-images generally yielded higher writing accuracy than Stroke Sequence immediately after learning. Notably, the advantage of the Pithy Formulas with Key-images over the Key-images on writing was specific to the participants that learned with visually similar pairs rather than those that learned with dissimilar pairs. All strategies were effective for reading, yet learners’ experience ratings favored the two form + meaning strategies over the strategy that focused primarily on form. Suggestions for future research and pedagogical implications on learning visually similar characters were offered. (shrink)

Several functional magnetic resonance imaging studies have demonstrated abnormalities in static intra- and interhemispheric functional connectivity among diverse brain regions in patients with major depressive disorder. However, the dynamic changes in intra- and interhemispheric functional connectivity patterns in patients with MDD remain unclear. Fifty-eight first-episode, drug-naive patients with MDD and 48 age-, sex-, and education level-matched healthy controls underwent resting-state fMRI. Whole-brain functional connectivity, analyzed using the functional connectivity density approach, was decomposed into ipsilateral and contralateral functional connectivity. We computed (...) the intra- and interhemispheric dynamic FCD using a sliding window analysis to capture the dynamic patterns of functional connectivity. The temporal variability in functional connectivity was quantified as the variance of the dFCD over time. In addition, intra- and interhemispheric static FCD patterns were calculated. Associations between the dFCD variance and sFCD in abnormal brain regions and the severity of depressive symptoms were analyzed. Compared to HCs, patients with MDD showed lower interhemispheric dFCD variability in the inferior/middle frontal gyrus and decreased sFCD in the medial prefrontal cortex/anterior cingulate cortex and posterior cingulate cortex/precuneus in both intra- and interhemispheric comparisons. No significant correlations were found between any abnormal dFCD variance or sFCD at the intra- and interhemispheric levels and the severity of depressive symptoms. Our results suggest intra- and interhemispheric functional connectivity alterations in the dorsolateral prefrontal cortex and default mode network regions involved in cognition, execution and emotion. Furthermore, our study emphasizes the essential role of altered interhemispheric communication dynamics in the DLPFC in patients with MDD. These findings contribute to our understanding of the pathophysiology of MDD. (shrink)

The RecA family proteins mediate homologous recombination, a ubiquitous mechanism for repairing DNA double‐strand breaks (DSBs) and stalled replication forks. Members of this family include bacterial RecA, archaeal RadA and Rad51, and eukaryotic Rad51 and Dmc1. These proteins bind to single‐stranded DNA at a DSB site to form a presynaptic nucleoprotein filament, align this presynaptic filament with homologous sequences in another double‐stranded DNA segment, promote DNA strand exchange and then dissociate. It was generally accepted that RecA family proteins function throughout (...) their catalytic cycles as right‐handed helical filaments with six protomers per helical turn. However, we recently reported that archaeal RadA proteins can also form an extended right‐handed filament with three monomers per helical turn and a left‐handed protein filament with four monomers per helical turn. Subsequent structural and functional analyses suggest that RecA family protein filaments, similar to the F1‐ATPase rotary motor, perform ATP‐dependent clockwise axial rotation during their catalytic cycles. This new hypothesis has opened a new avenue for understanding the molecular mechanism of RecA family proteins in homologous recombination. BioEssays 30:48–56, 2008. © 2007 Wiley Periodicals, Inc.

This study is intended to create an innovative contextual English learning environment making use of the widely used communication software, LINE ChatBot, based on the Artificial Intelligence Markup Language, in order to improve speaking and listening ability among learners. A total of 73 students were invited to participate in learning activities involving a 4-week English conversation exercise including both speaking and listening. Additionally, in order to explore the influence of competition on language acquisition, we added competition characteristics to the learning (...) activities in the experimental group to enhance learning motivation and learning outcomes. The results showed that with the help of the LINE ChatBot contextual learning environment, the performance of both groups of students was slightly enhanced, but no significant differences were found. Meanwhile, extrinsic motivation in both the experimental and control group was improved if they spoke anonymously. That is, the contextual learning environment based on the LINE ChatBot significantly improved the learners’ English speaking and listening ability. In addition, the results showed that the addition of a competition element effectively enhanced the learners’ intrinsic motivation to learn English on the LINE ChatBot. (shrink)

This co-edited volume compares Chinese and Western experiences of engineering, technology, and development. In doing so, it builds a bridge between the East and West and advances a dialogue in the philosophy of engineering. Divided into three parts, the book starts with studies on epistemological and ontological issues, with a special focus on engineering design, creativity, management, feasibility, and sustainability. Part II considers relationships between the history and philosophy of engineering, and includes a general argument for the necessity of dialogue (...) between history and philosophy. It continues with a general introduction to traditional Chinese attitudes toward engineering and technology, and philosophical case studies of the Chinese steel industry, railroads, and cybernetics in the Soviet Union. Part III focuses on engineering, ethics, and society, with chapters on engineering education and practice in China and the West. The book’s analyses of the interactions of science, engineering, ethics, politics, and policy in different societal contexts are of special interest. The volume as a whole marks a new stage in the emergence of the philosophy of engineering as a new regionalization of philosophy. This carefully edited interdisciplinary volume grew out of an international conference on the philosophy of engineering hosted by the University of the Chinese Academy of Sciences in Beijing. It includes 30 contributions by leading philosophers, social scientists, and engineers from Australia, China, Europe, and the United States. (shrink)
