In this paper, a discrete-time dynamic duopoly model, with nonlinear demand and cost functions, is established. The properties of existence and local stability of equilibrium points have been verified and analyzed. The stability conditions are also given with the help of the Jury criterion. With changing of the values of parameters, the system shows some new and interesting phenomena in terms to stability and multistability, such as V-shaped stable structures and different shape basins of attraction of coexisting attractors. The eye-shaped (...) structures appear where the period-doubling and period-halving bifurcations occur. Finally, by utilizing critical curves, the changes in the topological structure of basin of attraction and the reason of “holes” formation are analyzed. As a result, the generation of global bifurcation, such as contact bifurcation or final bifurcation, is usually accompanied by the contact of critical curves and boundary. (shrink)

This study aims to examine the neural correlates of cognitive shifting during the Dimensional Change Card Sort Task task with functional near-infrared spectroscopy. Altogether 49 children completed the DCCS tasks, and 25 children passing all items were classified into the Switch group. Twenty children committing more than one perseverative errors were grouped into the Perseverate group. The Switch group had Brodmann Area 9 and 10 activated in the pre-switch period and BA 6, 9, 10, 40, and 44 in the post-switch (...) period. In contrast, the Perseverate group had BA 9 and 10 activated in the pre-switch period and BA 8, 9, 10 in the post-switch period. The general linear model results afford strong support to the “V-shape curve” hypothesis by identifying a significant decrease–increase cycle in BA 9 and 44, the neural correlations of cognitive shifting.

At an early stage of its foundation, new China became clear about the nature of public welfare and quickly developed medical and health services, which was well received by the World Health Organization. The marketization and the reduction of input into medical and health services from the 1980s created severe adverse consequences. After the SARS' outbreak in 2003, China started to give serious consideration to its medical and health system, and to work at developing medical and health services. The new (...) healthcare reform launched in 2009 re-emphasizes fairness and public welfare, and China's achievements have been remarkable. Of course, there are still many problems to be solved in the reform, which also paves the way for increasing the reform in future. (shrink)

According to agency theory, agents base their economic decisions on self-interests when adverse selection conditions exist. However, cognitive moral development theory predicts that ethics/morals may influence decision-makers not to behave egoistically. Rutledge and Karim, 173-184) find both the moral reasoning level of the managers and an adverse selection condition affect a manager's project evaluation decisions significantly. Since prior studies have shown that national culture might influence the application of agency theory in project evaluation, this current study uses a different moral (...) development measurement to reexamine Rutledge and Karim's hypotheses in another culture. A total of 73 Taiwanese executive MBA students with an average of 12.17 years work experience participated in this study. We found that both moral development level and adverse selection conditions significantly affect managers' project continuance decisions. The interaction effect of these two factors indicates that, when adverse selection conditions exist, participants with a high level of moral development exhibit less of a tendency to continue an unprofitable project than those with a low level of moral development. With subjects from a different culture, our results confirm the findings of Rutldege and Karim. That is, the effects of moral development and adverse selection conditions on managers' project continuance decisions are robust and can be generalized to different cultures. Implications of the findings of this study to multinational firms are also discussed. (shrink)

The target article provides an intermediate account of culture and freedom that is conceived to be curvilinear by treating economic development not as an adaptive outcome in response to climate but as a cause of culture parallel to climate. We argue that the extent of environmental variability, including climatic variability, affects cultural adaptation.

This article explores how `social harmony' as cultural performance, is conducted by Chinese in their conversation at the surface level, with turbulence and manipulation concealed beneath superficial politeness. Although their more collective cultural orientation may lead them to greater cooperation and less confrontation, Chinese also develop artfully crafted messages to communicate competition and frustration. Selected discourse samples collected in Taiwan were analyzed in depth to show how social harmony may become a matter of external display, constructed, enacted and negotiated through (...) participants' verbal exchanges in their moment-to-moment interaction. It is concluded that superficial harmony allows the extensive web of interpersonal connections and hierarchical positioning to be maintained with minimal discord, while at the same time concealing underlying aggressiveness and ulterior motives.

Evidence supports predictive roles of non-social smartphone use for smartphone addiction, but the relationship of social smartphone use and smartphone addiction is unclear. This study explored whether social smartphone use has a double-edged impact on smartphone addiction. Using data from a sample of 909 Chinese undergraduates, we tested a parallel mediation model that considered online social support and realistic social support as mediators. As predicted, social smartphone use weakened smartphone addiction through realistic social support and contributed to smartphone addiction through (...) online social support. Moreover, we tested the moderating role of agreeableness in the mediation path of online social support. Agreeableness only moderated the indirect effects. Specifically, the predictive effects of online social support on smartphone addiction was greater for lower rather than higher agreeableness. The results suggest that social needs play an important role in the formation of smartphone addiction. Several limitations and implications are also discussed herein. (shrink)

Background: Healthcare workers in the front line of diagnosis, treatment, and care of patients with coronavirus disease 2019 are at great risk of both infection and developing mental health symptoms. This study aimed to investigate the following: whether healthcare workers in general hospitals experience higher mental distress than those in psychiatric hospitals; the role played by religion and alexithymic trait in influencing the mental health condition and perceived level of happiness of healthcare workers amidst the stress of the COVID-19 pandemic; (...) and factors that influence the resilience of healthcare workers at 6 weeks' follow-up.Methods: Four-hundred and fifty-eight healthcare workers were recruited from general and psychiatric hospitals, and 419 were followed-up after 6 weeks. All participants filled out the 20-item Toronto Alexithymia Scale, five-item Brief-Symptom Rating Scale, and the Chinese Oxford Happiness Questionnaire.Results: Under the stress of the COVID-19 pandemic, 12.3% of frontline healthcare workers in general hospitals reported having mental distress and perceived lower social adaptation status compared with those working in psychiatric hospitals. Christians/Catholics perceived better psychological well-being, and Buddhists/Taoists were less likely to experience mental distress. The results at 6 weeks of follow-up showed that the perceived lower social adaptation status of general hospital healthcare workers was temporary and improved with time. Christian/Catholic religion and time had independent positive effects on psychological well-being; however, the interaction of Christian/Catholic religion and time had a negative effect.Conclusions: Collectivism and individualism in the cultural context are discussed with regard to alexithymic trait and Buddhist/Taoist and Christian/Catholic religious faiths. Early identification of mental distress and interventions should be implemented to ensure a healthy and robust clinical workforce for the treatment and control of the COVID-19 pandemic. (shrink)

Having evolved to escape detection of deception completely, self-deception must respond to social conditions registering different probabilities of detection. To be adaptive, it must have a mechanism to keep truthful information temporarily from the self during deception and retrieve it after deception. The memory system may serve this mechanism and provides a paradigm in which to conduct research on self-deception.

Within the same pathogen-stress framework as proposed by Fincher & Thornhill (F&T), we argue further that pathogen stress promotes matrilocal rather than patrilocal family ties which, in turn, slow down the process of modernity; and that pathogen stress promotes social learning or copying, including the adoption of foreign religions.

It is necessary for us to know what erroneous thinking is before we discuss its relationship with existence. The so-called erroneous thinking, as I see it, refers to the opposite of correct thinking. If correct thinking means that man's comprehension of objective existence can lead to the grasping of the law of objective existence and can correspond with objective existence, erroneous thinking represents the failure of man's comprehension of objectivity to grasp the law of objective existence. Therefore erroneous thinking is (...) contradictory to, not corresponding with, objectivity. (shrink)

Peer assessment is employed as one fundamental practice of classroom-based assessment in terms of its learning-oriented and formative nature. The exercise of peer assessment has multiple and additional benefits for student learning. However, research into the learning processes in peer assessment is scarce both in theory and in practice, making it difficult to evaluate and pinpoint its value as a tool in assessment as learning. This study focuses both on the learning process and outcome through assessment activities. We set out (...) with three goals in mind: to examine students' assessment performance in context, to evaluate its impact on student progress, and to illuminate teachers on organizing assessment activities. Three specific research questions are answered in this study: How do student raters perform in the process of PA in an advanced English class? To what extent do assessment activities influence the students' speaking ability? What are students' perceptions of PA regarding its benefits and caveats? A total of 29 undergraduate students participated in two assessment activities on argumentative speaking. Many-Facet Rasch Model analysis was conducted to measure the rater effects both at the group level and the individual level. Bias/interaction analyses were performed to diagnose rater behavior in different contexts including the rating session, speaking session, and peer assessment vs. self-assessment. Questionnaire and semi-structured interview data were also collected to explore factors and strategies that could interfere with PA as AaL. Results show that students exhibited stable rating behavior and made progress in argumentative speaking in all dimensions, including delivery, organization, and language use. They are more stringent with themselves than with peers although there is one rare case with a bias against peers. Participants acknowledged the benefits of PA but also shared reasonable concerns in practice. This study validated the feasibility and the effectiveness of PA for student learning. Discussion on findings and guidelines for effective implementation of PA as AaL are provided. (shrink)

Transgender women experience serious psychiatric problems and high suicide rates. According to the interpersonal theory of suicide, thwarted belongingness and perceived burdensomeness play major roles in suicidality and can be measured by the Interpersonal Needs Questionnaire. However, no study has validated the use of the INQ in TGW. This study aimed to examine the psychometric properties of the INQ among TGW. We recruited 198 TGW from Shenyang, China, using snowball sampling. The construct validity of the INQ was assessed through factor (...) analysis, and convergent and divergent validity were examined through a structural equation model with other psychosocial factors. The construct validation analysis supported a three-factor model with satisfactory fit indices: χ2/df = 1.54, RMSEA = 0.052, CFI = 0.931, TLI = 0.916, SRMR = 0.053. The thwarted belongingness was significantly associated with self-esteem and social support, and the social exclusion was significantly associated with loneliness, depression, entrapment, and defeat, suggesting satisfactory convergent and divergent validity for the three-factor model. The present findings indicate that for TGW, high social exclusion is important in assessing perceived interpersonal needs, while the notable deviation from previous two-factor model warrants further study.

Sleep quality, personality, and cognitive load potentially increase second language writing anxiety and subsequently affect SLW achievement. This study investigates the predictions of sleep quality, personality, and cognitive load toward SLW anxiety and achievement in a computer-based test. Participants included 172 voluntary undergraduates majoring in English as foreign language. SLW anxiety in a computer-based test, sleep disturbance, personality and cognitive load was assessed with the SLW Anxiety Inventory, Pittsburg Sleep Quality Index, Type-D Personality, and cognitive load questionnaires. A structural equation (...) modeling approach was applied to examine the interdependence among the observed variables. An adequate-fit SLW anxiety model was built. The structural model showed that sleep disturbance, social inhibition personality, and computer-induced cognitive load were significant predictors of SLW anxiety in a computer-based test. Subsequently, SLW anxiety in a computer-based test and computer-induced cognitive load were significant negative predictors of computer-based SLW achievement. (shrink)

The salience of social risks and the incidence of various crises in China have induced widespread concerns among urban residents. Encountering frequent risks places higher demands on the cognition of urban residents. The concept of safety cognition capability is defined within the context of urban residents' daily life, and measurement instruments are developed and tested to lay the foundation for grasping the current safety cognition capability of urban residents and conducting further research. In this study, the five-dimensional structure of urban (...) residents' safety cognition capability was proposed by using the grounded theory method to sort out the interview transcript of interviews with 30 urban residents, and a 38-item URSCC scale was designed and used for surveys conducted in China. The results show that the scale can be used as a valid tool to measure the URSCC, and it can help city managers to better understand the safety needs of residents, as well as monitor the effectiveness of policy implementation.

A focus group study using four groups of food shoppers provides insights into consumers’ knowledge, beliefs, and behaviors regarding organic foods. Two focus groups consisted of shoppers who regularly bought organic foods and two focus groups of shoppers who predominantly purchased conventional foods. Participants in one of the conventional groups were all Caucasian; in the other they were all African-American. While familiarity with organic foods was much lower in the African-American group, its members were more receptive and positive towards organic (...) foods. Likewise, the African-American shoppers were more accepting of price premiums for organics foods. In comparing the two organic shopper groups with the two conventional shopper groups, it was found that the former were generally more knowledgeable about organic foods. They were also more likely to follow a special diet than conventional Caucasian shoppers. However, the behavior of organic shoppers varied widely. The research supports examining social justice and access as motivations for changing policies to support organic agriculture. (shrink)

In Risk and Luck in Medical Ethics Donna Dickenson explains in brilliant fashion the tension between ethics and luck, be it luck in outcomes of action on the one hand or luck in antecedent circumstances, in the problems that have to be faced, or character on the other. According to Dickenson, most of the philosophical debate so far has focused on how luck in outcomes affects agents’ ability to act as morally responsible people. But Dickenson thinks it is equally important (...) to discuss how to modify one’s own luck through character development and environmental changes.Throughout her lively inquiry, packed with interesting real life case studies, Dickenson requires her readers to consider philosophers’ desire “to minimize the effects of chance on moral character and the rightness of ethical choices” , a desire so intense that it led Kant to proclaim that even if the good will was “…wholly lacking in power to accomplish its purposes … it would [still] sparkle like a jewel in its own right, as something that had full worth in itself” . Philosophers want to believe that human beings control their own destiny. Yet they fear that nothing is really in their own control, and that the foundation of morality—autonomy, choice, freedom—is illusory.Dickenson claims that we can both acknowledge the role luck and risk play in our lives and maintain a robust Kantian sense of self if we properly limit that for which we are responsible . Moral agents are not responsible for all the outcomes of their actions, but only for some. Similarly, moral agents are not responsible for the way they initially find themselves in the world; but they are responsible …. (shrink)

We study the relationship between corporate social performance and financial performance by comparing the portfolio returns of firms with changes in corporate social responsibility (CSR) intensity. Using an extensive US sample from the MSCI ESG database, we find that improvement in the overall CSR is generally value enhancing. The relationship varies with CSR dimensions. More importantly, the relationship shifts differently for various CSR dimensions during the crisis period when trust in the society is low and financial resource is limited. Improvement (...) in environment, human rights, and product characteristics shows higher financial returns during the financial crisis period, whereas the value enhancement of improvement in employee relations is more pronounced during the non-crisis period.

Objective: The objective of this study was to evaluate the psychometric properties of the Chinese version of the decision regret scale. Methods: The data of 704 patients who completed the DRSc were used for the analyses. We evaluated the construct, convergent/discriminant, and known-group validity; internal consistency and test–retest reliability; and the item invariance of the DRSc. A receiver operating characteristic curve was employed to confirm the optimal cutoff point of the scale. Results: A confirmatory factor analysis indicated that a one-factor (...) model fits the data. The internal consistency and test–retest reliability [intraclass correlation coefficient = 0.71] of the DRSc were acceptable. The DRSc demonstrated unidimensionality and invariance for use across the sexes. It was confirmed that an optimal cutoff point of 25 could discriminate between patients with high and low decisional regret during clinical practice. Conclusion: The DRSc is a parsimonious instrument that can be used to measure the uncertainty inherent in medical decisions. It can be employed to provide knowledge, offer support, and elicit patient preferences in an attempt to promote shared decision-making. (shrink)

This essay discusses the history of the "futility debate" and the motives that sometimes prompt health care professionals, health care providers, patients, and surrogates to take different sides in it. Changes in the health care system, financial responsibility shifts, technical medical advances, and medical care rationing are analyzed as contributors to the futility debate. So too are variations in the definition of futility examined as part of the current controversy. The respective attitudes of professionals, providers, patients, and surrogates in accepting (...) the goals, capabilities, and limits of medicine are also explored. In particular, the lack of honest communication between health care professionals/health care providers on the one hand and patients/surrogates on the other is acknowledged as a major roadblock in the building of care-focused futility policies. Finally, various initial attempts of hospitals to create futility guidelines are evaluated in order to detect problem areas and to suggest lines of improvement.

BackgroundThe number of students enrolled in higher education in China accounts for more than one-fifth of the world, and universities, as a community of faculty, staff and scholars, currently do not have a scale that specifically assesses the well-being of the population in the environment of Chinese universities. However, the University of Pittsburgh has developed a comprehensive well-being scale, referred to as the Pitt Wellness Scale, specifically to measure people’s well-being in a university environment.AimsInvestigate the psychometric properties of the Pitt (...) Wellness Scale in Chinese university environmental samples.MethodsThe original scale was culturally adapted and modified through expert consultation, a random sample of 1870 current faculty, staff, and students were selected for the questionnaire survey. Exploratory factor analysis and confirmatory factor analysis were used to investigate the potential factor structure of the Chinese Revision of the Pitt Wellness Scale and to measure its reliability and validity. Finally, the factors that affect people’s well-being in the Chinese university environment were explored.ResultsThe Chinese Revision of the Pitt Wellness Scale retained 30 items, and the EFA supports a five-factor structure, which differed from the results of the original scale, and the CFA results showed that the model fitted well. The discriminant validity of the modified Chinese scale was excellent. The overall Omega coefficient of the scale was 0.958, and the reliability of the retest after 4 weeks was 0.821.ConclusionThe Chinese Revision of the Pitt Wellness Scale possesses satisfactory psychometric properties, and it can be considered an instrument for assessing personal well-being in Chinese university environment.

Purpose: to characterize ethics course content, structure, resources, pedagogic methods, and opinions among academic administrators and course directors at U.S. medical schools. Method: An online questionnaire addressed to academic deans and ethics course directors identified by medical school websites was emailed to 157 Association of American Medical Colleges member medical schools in two successive waves in early 2022. Descriptive statistics were utilized to summarize responses. Results: Representatives from 61 (39%) schools responded. Thirty-two (52%) respondents were course directors; 26 (43%) were (...) deans of academic affairs, medical education, or curriculum; and 3 with other roles also completed the survey (5%). All 61 schools reported some form of formal ethics education during the first year of medical school, with most (n = 54, 89%) reporting a formal mandatory introductory course during preclinical education. Schools primarily utilized lecture and small-group teaching methods. Knowledge-based examinations, attendance, and participation were most commonly used for assessment. A large majority regarded ethics as equally or more important than other foundational courses, but fewer (n = 37, 60%) provided faculty training for teaching ethics. Conclusions: Despite a response rate of 39 percent, the authors conclude that medical schools include ethics in their curricula in small-group and lecture formats with heterogeneity regarding content taught. Preclinical curricular redesigns must innovate and implement best practices for ensuring sound delivery of ethics content in future curricula. Additional large-scale research is necessary to determine said best practices. (shrink)
