The longitudinal, qualitative study aimed to explore the lived experiences of Chinese university emerging adults by analyzing their personal life stories, reflective journals, and semi-structured interview data collected over a 2-year period. A qualitative content analysis was used to identify five themes: maturity, academic performance, interpersonal communication skills, social support network, and sense of loss. The study found that the growth in emerging adulthood was dynamic, positive, and multifaceted. The study demonstrated that writing personal life stories, as a practice of (...) meaningful literacy instruction in EFL contexts, helped students to record a memorable past, reconcile with the past, and strive for personal growth. These findings suggest that emerging adults’ personal growth be stressed in foreign language teaching to promote Chinese university emerging adults’ growth and development. It is also suggested that personal life stories be used in foreign language teaching under the guidance of meaningful literacy instruction. (shrink)

Globalization is a part of modern life. Sharing a common set of professional nursing values is critical in this global environment. The purpose of this research was to examine the professional values of nursing students from two distinct cultural perspectives. Nurse educators in Taiwan partnered with nurse educators in the United States to compare professional values of their respective graduating nursing students. The American Nurses Association Code of Ethics served as the philosophical framework for this examination. The convenience sample comprised (...) 94 Taiwanese students and 168 US students. Both groups reported high scores on an overall measure of values. They did differ substantially on the relative importance of individual items related to advocacy, competence, education, self-evaluation, professional advancement, and professional associations. Global implications for the collaborative practice of nurses from different cultures working together can be improved by first recognizing and then attending to these differences in value priorities.

In lieu of an abstract, here is a brief excerpt of the content:258 Feminist Studies 47, no. 2. © 2021 by Feminist Studies, Inc. Mei-Hua Chen and Hong-zen Wang Flexible Intimacies in the Global Intimate Economy: Evidence from Taiwan’s Cross-Border Marriages When Lin Ping was interviewed by the first author of this article at a detention center in the southern city of Tainan, Taiwan, in September 2006, she was forty-three. At that time, she had been married to a Taiwanese (...) man for five years and had successfully obtained a permit for employment at a factory, earning NT$27,000 a month for working ten hours a day. However, before having obtained the work permit, Lin managed to find jobs in informal sectors as a cleaner, a care worker, and a stall vendor’s helper, earning NT$15,000 a month. By the time of our interview, Lin had gone to work at a brothel because she could not put up with her husband anymore. Lin’s husband is twenty years older than she is and, as she described their relationship, the huge age gap makes communication between the couple difficult. They fought often and fiercely. During those fights, Lin’s husband would threaten to divorce her and to not renew her application for residency, which would result in her immediate deportation to China. This did happen once when Lin’s husband refused to renew her work permit. As a result, Lin overstayed her visa and lost her job at the factory. Being thus unemployed, Lin had to dip into her savings and risked going into debt. Her dire financial situation caused her anxiety. Losing the regular income provided by her factory job meant not only having nothing to live on but also being unable to send money back home to China. Given that her marriage failed to provide her the work permit she needed, Lin wanted to leave her husband Mei-Hua Chen and Hong-zen Wang 259 and “go out” for her own good. When asked what she thinks of the stigma attached to commercial sex, Lin replied, “I need to be able to feed myself first. But if you don’t have a work permit and a job, it [sex work] is the only way out. So, I thought I would do it.” She continued: “Once I had the money, I would be able to run a small business such as a noodle stall or selling steam dumplings.” Lin Ping’s stories serve to sketch out the interconnectedness between cross-border sex work and cross-border marriage. As her experiences show, cross-border sex work and marriage tend to overlap in certain spheres; however, they are more often than not conceptualized as two separate institutions. Both are grouped under already dichotomized migratory categories such as marriage migrants and economic migrants, real marriage and fake marriage, legal workers and workers without permits, and legal and illegal migrants, etc. Such dichotomization downplays the fact that many marriage migrants, like economic migrants, invest great economic interests in cross-border marriages; it also downplays the fact that migrant sex workers might also be involved in having intimate relationships with someone. Apart from the entanglement of monetary exchange and intimacy, cross-border marriage and cross-border sex work are also parts of a global intimate economy in which the Global North appropriates southern women’s reproductive and intimate labor. Seen in this light, it becomes urgent to theorize how women from the South manage to survive in the global intimate economy by shifting between cross-border marriage and cross-border sex work in the North. Admittedly, such a Global North-and-South framework fits awkwardly when it comes to understanding Taiwan’s situation because economic development is the sole barometer used to define the North and the South, and economically, Taiwan should be in the North camp. Politically, however, due to the majority of nations not recognizing its sovereignty, Taiwan is much more peripheral than most southern countries, let alone China. Therefore, compared to countries in Southeast Asia, Taiwan is economically North but politically South. This semi-peripheral position in the North-South framework, in our view, makes Taiwan a unique case to theorize the global intimate economy. As a tactic... (shrink)

Professional values are standards for action and provide a framework for evaluating behavior. This study examined changes in the professional values of nursing students between their entrance to and graduation from an undergraduate nursing program. A pre- and post-test design was employed. A convenience sample of 94 students from a university in Taiwan was surveyed. Data were collected from students during the sophomore and senior years. Total scores obtained for the revised Nurses Professional Values Scale during the senior year of (...) the nursing program were significantly higher than upon program entry. The ‘caring’ subscale was scored highest at both program entry and graduation, but the pre- and post-test scores were not significantly different from each other. The students scored significantly higher on the ‘professionalism’ and ‘activism’ subscales at post-test than they did at pre-test. Professional values changed in a positive direction between the beginning of the student nurses’ educational experience and their graduation. The results supported the premise that education had a positive effect on these students’ professional values but causality could not be assumed. (shrink)

Clinical studies as well as hundreds of case reports have indicated that Yan Xin Life Science Technology has enabled human participants to live a normal life with little or no food intake for prolonged periods—a state referred to as bigu. Bigu is described in historical records as “taking in qi to avoid food,” and is regarded as a special technique to achieve a long and healthy life. In this study, experiments were designed to study whether cells in vitro can survive (...) without commonly acknowledged essential nutrients after receiving external qi treatments from Dr. Yan Xin, a chief physician and a renowned life scientist. Results reported here indicate that mouse hybridoma cells can survive in Dulbeco’s modified Eagles medium without serum or in phosphate-buffered saline buffer without other nutrient ingredients after qi treatment. These results are the first evidence that a cellular equivalent of the human bigu phenomenon or cellular bigu phenomenon may occur. (shrink)

Anxious major depressive disorder is a common subtype of major depressive disorder; however, its unique neural mechanism is not well-understood currently. Using multimodal MRI data, this study examined common and specific alterations of amygdala subregions between patients with and without anxiety. No alterations were observed in the gray matter volume or intra-region functional integration in either patient group. Compared with the controls, both patient groups showed decreased functional connectivity between the left superficial amygdala and the left putamen, and between the (...) right superficial amygdala and the bilateral anterior cingulate cortex and medial orbitofrontal cortex, while only patients with anxiety exhibited decreased activity in the bilateral laterobasal and superficial amygdala. Moreover, the decreased activity correlated negatively with the Hamilton depression scale scores in the patients with anxiety. These findings provided insights into the pathophysiologic processes of anxious major depressive disorder and may help to develop new and effective treatment programs. (shrink)

Two kinds of probability expressions, verbal and numerical, have been used to characterize the uncertainty that people face. However, the question of whether verbal and numerical probabilities are cognitively processed in a similar manner remains unresolved. From a levels-of-processing perspective, verbal and numerical probabilities may be processed differently during early sensory processing but similarly in later semantic-associated operations. This event-related potential (ERP) study investigated the neural processing of verbal and numerical probabilities in risky choices. The results showed that verbal probability (...) and numerical probability elicited different N1 amplitudes but that verbal and numerical probabilities elicited similar N2 and P3 waveforms in response to different levels of probability (high to low). These results were consistent with a level-of-processing framework and suggest some internal consistency between the cognitive processing of verbal and numerical probabilities in risky choices. Our findings shed light on possible mechanism underlying probability expression and may provide the neural evidence to support the translation of verbal to numerical probabilities (or vice versa).

This study draws on Relevance Theory, Conversation Analysis, and Politeness Theory in investigating a full range of discourse functions for hao and dui with reference to recurrent patterns, distributions, and forms of organization in a large corpus of talk. Special emphasis is placed on a comparison of hao and dui in combination with a small subset of discourse particles: in particular hao/hao le/ hao la/hao a/hao ba and dui/dui a/dui le in spoken discourse. We find that both of the markers (...) signal special sequential relatedness in talk and carry information which is relevant in determining the boundaries of conversational exchange. However, in interaction hao is used for expressing acceptance of the other speaker’s move or act, whereas dui conveys acknowledgment of the propositional content of the utterance produced by the other speaker.

Discourse marker analysis has been widely studied, leading Fraser to call this subject `a growth market in linguistics'. In our present research, we extended the study of discourse markers to the Chinese marker meiyou, which has traditionally been treated as a negator. The corpus studied here contains 40 conversations, totaling 482'27”. The analytical framework adopted in the study was drawn from van Dijk's model, which mainly consists of a semantic/textual level and a pragmatic/interactional level. A total of 141 occurrences of (...) meiyou were identified as discourse markers in the corpus: 13 of them occur at the textual level and 128 of them at the interactional level. Thus, meiyou occurs more frequently at the interactional level than at the textual level. At the textual level, meiyou introduces an answer to a self-inquiry or self-correction. At the interactional level, meiyou mainly serves as a response to provide information, as a marker of correction/clarification or evasion, and as a response to praise or gratitude. In particular, with respect to meiyou's interactive functions, we use the concepts of preference structure and face-threatening acts to analyze the collected data. We further demonstrate that intersubjectification, a mechanism whereby meanings become more centered on the addressee, is involved in the development of the discourse marker meiyou. (shrink)

BackgroundAt present, tic disorder has attracted the attention of medical researchers in many countries. More clinicians choose non-drug therapy, especially cognitive-behavioral therapy because of the cognitive side effects of drug therapy. However, few studies had assessed its efficacy. It is necessary to have a more comprehensive understanding of the literature quality of CBT and its intervention effect.MethodsIn this study, MEDLINE, Embase, and Cochrane were searched from the beginning to June 15, 2021 to study the efficacy of -CBT on tic disorder. (...) Only studies using the Yale Global Tic Severity Scale and the control group were included.ResultsA total of 12 randomized controlled trials, including 536 patients with tic disorders, were identified. The results showed that the effect of CBT was better than that of the control group. The pooled standardized mean difference was −0.34. The effect size of CBT differs from different intervention conditions. In seven studies, the subjects’ motor tic scores were counted. The sample size of the experimental group was 224 and that of the control group was 218. The pooled SMD was −0.43. Seven studies counted the vocal tic scores of subjects, 224 in the experimental group and 218 in the control group. The pooled SMD was −0.22. Seven studies counted the tic impairment scores of subjects, 220 in the experimental group and 214 in the control group. The pooled SMD was −0.48.ConclusionThe literature shows that different CBTs can significantly reduce the total score of tic disorder and the score of motor tic, but cannot significantly reduce the score of vocal tic. In the future, more new interventions were needed to improve the symptoms of different patients, especially vocal tic. (shrink)

In this paper, the stabilization problem of nonholonomic chained-form systems is addressed with uncertain constants. In this paper, the active disturbance rejection control is designed to solve this problem. The proposed control strategy combines extended state observer and adaptive sliding mode controller. The control of nonholonomic chained-form systems with dynamic nonlinear uncertain terms and uncertain constants is first discussed in this paper. In comparison with existing methods, the proposed method in this paper has better performance. It is proved that, with (...) the application of the proposed control strategy, semiglobal finite-time stabilization of the systems is achieved. An example is given to illustrate the effectiveness of the proposed method. (shrink)

BackgroundWith the popularity of computers, the internet, and the global spread of COVID-19, more and more attention deficit hyperactivity disorder patients need timely interventions through the internet. At present, there are many online intervention schemes may help these patients. It is necessary to integrate data to analyze their effectiveness.ObjectivesOur purpose is to integrate the ADHD online interventions trials, study its treatment effect and analyze its feasibility, and provide reference information for doctors in other institutions to formulate better treatment plans.MethodsWe searched (...) PubMed, EMBASE and Cochrane libraries. We didn't limit the start date and end date of search results. Our last search was on December 1, 2021. The keyword is ADHD online therapy. We used the Cochrane bias risk tool to assess the quality of included studies, used the standardized mean difference as an effect scale indicator to measure data. Random effects model, subgroup analysis were used to analyze the data.ResultsSix randomized controlled trials were identified, including 261 patients with ADHD. These studies showed that online interventions was more effective than waiting list in improving attention deficit and social function of adults and children with ADHD. The attention deficit scores of subjects were calculated in six studies. The sample size of the test group was 123, the sample size of the control group was 133, and the combined SMD was −0.73. The social function scores of subjects were calculated in six studies. The sample size of the experimental group was 123 and the control group was 133. The combined SMD was −0.59.ConclusionsThe results show that online interventions of ADHD may be an effective intervention. In the future, we need more online intervention researches to improve the symptoms of different patients, especially for some patients who have difficulties in accepting face-to-face treatment.

It was meaningful to predict the customers' decision-making behavior in the field of market. However, due to individual differences and complex, non-linear natures of the electroencephalogram signals, it was hard to classify the EEG signals and to predict customers' decisions by using traditional classification methods. To solve the aforementioned problems, a recurrent t-distributed stochastic neighbor embedding neural network was proposed in current study to classify the EEG signals in the designed brand extension paradigm and to predict the participants' decisions. The (...) recurrent t-SNE neural network contained two steps. In the first step, t-SNE algorithm was performed to extract features from EEG signals. Second, a recurrent neural network with long short-term memory layer, fully connected layer, and SoftMax layer was established to train the features, classify the EEG signals, as well as predict the cognitive performance. The proposed network could give a good prediction with accuracy around 87%. Its superior in prediction accuracy as compared to a recurrent principal component analysis network, a recurrent independent component correlation algorithm [independent component analysis ] network, a t-SNE support vector machine network, a t-SNE back propagation neural network, a deep LSTM neural network, and a convolutional neural network were also demonstrated. Moreover, the performance of the proposed network with different activated channels were also investigated and compared. The results showed that the proposed network could make a relatively good prediction with only 16 channels. The proposed network would become a potentially useful tool to help a company in making marketing decisions and to help uncover the neural mechanisms behind individuals' decision-making behavior with low cost and high efficiency.

ObjectivesSeveral studies have examined the effects of repetitive transcranial magnetic stimulation (rTMS) on associative memory (AM) but findings were inconsistent. Here, we aimed to test whether twice-daily rTMS could significantly improve AM.MethodsIn this single-blind, sham-controlled experiment, 40 participants were randomized to receive twice-daily sham or real rTMS sessions for five consecutive days (a total of 16,000 pulses). The stimulation target in left inferior parietal lobule (IPL) exhibiting peak functional connectivity to the left hippocampus was individually defined for each participant. Participants (...) completed both a picture-cued word association task and Stroop test at baseline and 1 day after the final real or sham rTMS session. Effects of twice-daily rTMS on AM and Stroop test performance were compared using two-way repeated measures analysis of variance with main factors Group (real vs. sham) and Time (baseline vs. post-rTMS).ResultsThere was a significant Group × Time interaction effect. AM score was significantly enhanced in the twice-daily real group after rTMS, but this difference could not survive the post hoc analysis after multiple comparison correction. Further, AM improvement in the twice-daily real group was not superior to a previously reported once-daily rTMS group receiving 8,000 pulses. Then, we combined the twice- and once-daily real groups, and found a significant Group × Time interaction effect. Post hoc analysis indicated that the AM score was significantly enhanced in the real group after multiple comparisons correction.ConclusionOur prospective experiment did not show significant rTMS effect on AM, but this effect may become significant if more participants could be recruited as revealed by our retrospective analysis.

This study aimed to analyze the mediating effect of tolerance of uncertainty and trait anxiety on future self-continuity and intention to use Internet wealth management systems. A questionnaire survey was distributed online and a total of 388 participants completed questionnaire, The questionnaire included the following scales: Chinese version of the FSC, Intention to Use the Internet Wealth Management, TU, and TA. Pearson correlation was used to investigate the correlation coefficient between variables while the sequential regression method was used to analyze (...) relationship between variables. To analyze the collected data, the SPSS 26.0 was used. A two-step procedure was applied to analyze the mediation effect. Confirmatory factor analysis was conducted to test the measurement model. Afterward, the Maximum Likelihood method was used for path analysis, and the Bias-corrected Bootstrap method was used to investigate determine the estimated value and confidence interval of the mediating effect. To analyze the mediation effect, the Mplus 7.0 was used. The results showed that FSC positively predicted individuals’ Internet wealth management systems. Furthermore, TU and TA played complete serial multiple mediating roles between FSC and IUIWM. The role of TA and TU have negative impact on intention to use. This study provides a theoretical basis in personality psychology that Internet financial product suppliers can use to improve the attractiveness of their products. Product managers can subdivide users according to these personality traits to provide customized products. (shrink)

This dissertation addresses the roots of fundamental changes in twentieth-century art in China by addressing how the cultural exchange between Europe and China transformed critical conceptions and artistic practices in the field of art. The translation of German aesthetic theories and the French academic training of Chinese artists engendered the conceptual and technical transformation of Chinese art in the early twentieth century. While the notions of pure nudity, artistic salvation, and archaeology of art were introduced from German philosophy into Chinese (...) art, the traditional ideas of art versus craft and artist as moral exemplars were converted. Chinese intellectuals analogized crisis-ridden China in the early 20th century to Germany being occupied by the Napoleon army in 1806. They believed that the superior academic culture, instead of its political and military strengths, was the foundation of the unification of Germany in 1871. The doctrines of German scholars were therefore introduced to China through German-trained Chinese intellectuals, aiming at achieving the modern transition of Chinese society. The implementation of aesthetic education based on German philosophical theories endowed modern artists and their works with the social mission to shape the citizens’ personalities and improve their tastes to establish a liberal and civilized modern Chinese society. Moreover, due to the establishment of the Institut Franco-Chinois in Lyon, more Chinese art students acquired the opportunity to study in Paris, the most important center for new artistic ideas and practices during the early twentieth century. Thus, the conceptual shift in the field of aesthetics was expressed through artists with a French academic training background. This study focuses on examining how the translation of German aesthetic doctrines and the introduction of French (sometimes Italian) artistic techniques contributed to the modern transition of Chinese art. How were German aesthetics translated and disseminated to young Chinese artists in the early twentieth century? How were the German scholars’ theories appropriated to establish new standards for evaluating artists and their works? What were the mechanisms, obstacles and cultural clashes encountered by European-trained Chinese artists in their training and creation processes? How did European-trained Chinese artists respond to these new modern aesthetic doctrines? Each of the five chapters of my dissertation centers on the introduction or transformation of an artistic concept: art versus craft, pure nudity, artistic salvation, and archaeology of art, discussing how these concepts were theoretically and practically formulated in Chinese art.

Gender plays an important role in various aspects of second language acquisition, including lexicon learning. Many studies have suggested that compared to males, females are less likely to experience boredom, one of the frequently experienced deactivating negative emotions that may impair language learning. However, the contribution of boredom to gender-related differences in lexicon learning remains unclear. To address this question, here we conducted two experiments with a large sample of over 1,000 college students to explore the relationships between gender differences (...) in boredom and lexicon learning. In Experiment 1, a cohort of 527 participants completed the trait and state boredom scales as well as a novel lexicon learning task without awareness of the testing process. In Experiment 2, an independent cohort of 506 participants completed the same novel lexicon learning task with prior knowledge of the testing procedure. Results from both experiments consistently showed significant differences between female and male participants in the rate of forgetting words and the state boredom scores, with female participants performing better than male participants. Furthermore, differences in state boredom scores partially explained differences in the rate of forgetting words between female and male participants. These findings demonstrate a novel contribution of state boredom to gender differences in lexicon learning, which provides new insights into better language-learning ability in females. (shrink)

The question of what determines brain laterality for auditory cognitive processing is unresolved. Here, we demonstrate a swap of hemisphere dominance from right to left during semantic interpretation of Chinese lexical tones in native speakers using simultaneously recorded mismatch negativity response and behavioral reaction time during dichotic listening judgment. The mismatch negativity, which is a brain wave response and indexes auditory processing at an early stage, indicated right hemisphere dominance. In contrast, the behavioral reaction time, which reflects auditory processing at (...) a later stage, indicated a right ear listening advantage, or left hemisphere dominance. The observed swap of hemisphere dominance would not occur when the lexical tone was substituted with a meaningless pure tone. This swap reveals dependence of hemisphere labor division initially on acoustic and then on functional cues of auditory inputs in the processing from sound to meaning. (shrink)

Yan Xin Life Science Technology-Optimized Caloric Restriction (YXLST-CR) is a unique food abstinence, which suppresses appetite and sensation of hunger while maintaining physiological homeostasis. The authors review the first clinical case study on YXLST-CR, or YXLST-bigu, a 15-day, 24-hour observation in 1987 on a 21-year-old female undergoing YXLST-bigu for several months. The participant took no food or water and conducted normal physical activities. The daily records of body weight, temperature, pulse rate, blood pressure, and daily urine test results showed no (...) abnormalities. Homeostasis was maintained during YXLST-CR. The authors also report serum leptin levels in a group of individuals undergoing YXLST-CR and a control group before and after a 24-hour water-only period. The leptin level prior to the observation for the YXLST-CR group was lower than that for the control group and remained unchanged during the observation, suggesting the possibilities of an established metabolic adaptation.

The present study examined the effects of transcranial direct current stimulation using Halo Sport on the time to exhaustion in relation with muscle activities and corticomuscular coupling of agonist and antagonist muscles during a sustained isometric fatiguing contraction performed with the elbow flexors. Twenty healthy male college students were randomly assigned to tDCS group and control group. The two group participants performed two experimental sessions which consisted of pre-fatigue isometric maximal voluntary contraction, sustained submaximal voluntary contractions performed to exhaustion, and (...) post-fatigue MVC with the right elbow flexor muscles. Sham stimulation and tDCS were applied for control and tDCS group participants 20 min prior to the second session test, respectively. MVC strength in pre- and post-fatigue test, TTE, electroencephalogram, and electromyography of biceps brachii and triceps brachii were recorded during the tests. It was found that tDCS using the Halo Sport device significantly increased TTE and thus improved muscular endurance performance. The improvement may be partly related to the improvement of neuromuscular efficiency as reflected by decrease of antagonistic muscle coactivation activities, which may be related to cortical originated central processing mechanism of neuromuscular activities.
