IntroductionRace-walking is a sport that mimics normal walking and running. Previous studies on sports science mainly focused on the cardiovascular and musculoskeletal systems. However, there is still a lack of research on the central nervous system, especially the real-time changes in brain network characteristics during race-walking exercise. This study aimed to use a network perspective to investigate the effects of different exercise intensities on brain functional connectivity.Materials and methodsA total of 16 right-handed healthy young athletes were recruited as participants in (...) this study. The cerebral cortex concentration of oxyhemoglobin was measured by functional near-infrared spectroscopy in the bilateral prefrontal cortex (PFC), the motor cortex (MC) and occipital cortex (OC) during resting and race-walking states. Three specific periods as time windows corresponding to different exercise intensities were divided from the race-walking time of participants, including initial, intermediate and sprint stages. The brain activation and functional connectivity (FC) were calculated to describe the 0.01-0.1 Hz frequency-specific cortical activities.ResultsCompared to the resting state, FC changes mainly exist between MC and OC in the initial stage, while PFC was involved in FC changes in the intermediate stage, and FC changes in the sprint stage were widely present in PFC, MC and OC. In addition, from the initial-development to the sprint stage, the significant changes in FC were displayed in PFC and MC.ConclusionThis brain functional connectivity-based study confirmed that hemodynamic changes at different exercise intensities reflected different brain network-specific characteristics. During race-walking exercise, more extensive brain activation might increase information processing speed. Increased exercise intensity could facilitate the integration of neural signals such as proprioception, motor control and motor planning, which may be an important factor for athletes to maintain sustained motor coordination and activity control at high intensity. This study was beneficial to understanding the neural mechanisms of brain networks under different exercise intensities. (shrink)

With the development of deep neural networks, automatic music composition has made great progress. Although emotional music can evoke listeners' different auditory perceptions, only few research studies have focused on generating emotional music. This paper presents EmotionBox -a music-element-driven emotional music generator based on music psychology that is capable of composing music given a specific emotion, while this model does not require a music dataset labeled with emotions as previous methods. In this work, pitch histogram and note density are extracted (...) as features that represent mode and tempo, respectively, to control music emotions. The specific emotions are mapped from these features through Russell's psychology model. The subjective listening tests show that the Emotionbox has a competitive performance in generating different emotional music and significantly better performance in generating music with low arousal emotions, especially peaceful emotion, compared with the emotion-label-based method.

Using data from the China Education Panel Survey, which was a nationally representative sample of junior high school students, this study examined the association of internal migration with depression among migrant and left-behind children, while exploring the moderating effect of gender difference and the mediating effects of social relationships. The results showed that migrant children had a significantly lower level of depression than left-behind children. Further, the difference in mental health between migrant children and left-behind children was more prominent for (...) boys than girls. The mechanism analyses indicated that compared to left-behind children, internal migration positively predicted parent–child relationships and peer relationships of migrant children, which in turn reduced their depressive symptoms. Although migrant children suffered from a higher level of teacher discrimination than their left-behind counterparts, it had no significant relationship with depression after controlling for children’s social relationships with parents and peers. Our findings suggested that migrating with parents was helpful to reduce children’s depressive symptoms in comparison with being left behind. Therefore, actions should be implemented to reduce the occurrence of involuntary parent–child separation and the prevalence of children’s depressive disorders due to institutional constraints. In addition, necessary treatments are needed to improve the psychological wellbeing of disadvantaged children, especially among left-behind children with mental illness. (shrink)

This paper investigates the aperiodic sampled-data control for a chaotic system. Firstly, Takagi–Sugeno fuzzy models for the chaotic systems are established. The lower and upper bounds of the sampling period are taken into consideration. Then, the criteria for mean square exponential stability analysis and aperiodic sampled-data controller synthesis are provided by means of linear matrix inequalities. And the real sampling patterns can be fully captured by constructing suitable Lyapunov functions. Finally, an illustrative example shows that the proposed method is effective (...) to guarantee that the system’s states are stable with aperiodic sampled data. (shrink)

Most discussions of racial fetish center on the question of whether it is caused by negative racial stereotypes. In this paper I adopt a different strategy, one that begins with the experiences of those targeted by racial fetish rather than those who possess it; that is, I shift focus away from the origins of racial fetishes to their effects as a social phenomenon in a racially stratified world. I examine the case of preferences for Asian women, also known as ‘yellow (...) fever’, to argue against the claim that racial fetishes are unobjectionable if they are merely based on personal or aesthetic preference rather than racial stereotypes. I contend that even if this were so, yellow fever would still be morally objectionable because of the disproportionate psychological burdens it places on Asian and Asian-American women, along with the role it plays in a pernicious system of racial social meanings.

In response to the great crises of the COVID-19 coronavirus, virtually all new technologies protected by patent rights have been used in practice from diagnostics, therapeutic, medical equipment, and vaccine to prevention, tracking, and containment of COVID-19. However, the moral justification of patent rights is questioned when pharmaceutical patents conflict with public health. This paper proposes a revised approach of deciding on how to address the conflicts between business ethics and patent protections and then compares the different mechanisms of clearing (...) patent thickets. Our findings highlight that patent pledges may not only contribute to achieving the maximized substantive justice of the public but also help patent pledgors fulfill procedural justice. The advantages of patent pledges have attracted many patent holders to make public statements during the COVID-19 pandemic. In contrast, the disadvantages of a free license may make patent pledges not sustainable for a long time without the related supporting measures. Our findings will be helpful for policymakers or company managers to make an appropriate decision on rationally utilizing patent portfolios for fighting against public health crises. (shrink)

Teachers as the most important elements of education constantly need professional development courses in order to improve their pedagogy and practice. Given this, many educational systems worldwide have paid special attention to designing courses by which the quality of teaching and learning raises considerably. This surge of interest has ended in different studies on PD programs in L2 education. However, the pertinent literature lacks a comprehensive review of the models, applications, and impacts of EFL/ESL teachers' PD and various aspects influenced (...) by this construct. To fill this gap and add fresh insights into this strand of research, the present study aimed to review the definitions, characteristics, models, goals, and uses of teacher professional development in L2 education. Moreover, several empirical studies were touched on to support the claims of TPD impact on teachers. Finally, the study presented different implications for L2 teachers, teacher trainers, researchers, and policy-makers who can realize the significance and impact of effective TPD courses on the whole process of teaching and learning.

Q methodology has been used in a variety of fields to employ a scientific approach to dealing with subjectivity; yet, its use has just gained momentum in the second language acquisition domain recently. The present paper argues that Q methodology is remarkably efficient in representing the dynamic quality of complex systems involved in the language learning process, which is, thus, compatible with the complexity and dynamic systems theory. As Q methodology enjoys advantages of both qualitative and quantitative lines of research, (...) it helps to explore and reflect L2 learners’ subjective views and perceptions about their emotions in an L2 class in a comprehensive manner. With the current growing attention to individuals’ emotional experiences in recent years, SLA research domain is ripe for many scientific inquiries about L2 learners’ affective variables benefiting from this method. The few existing studies in the L2 domain have had interesting findings, which show the Q methodology should be more extensively used in the field to reveal facts about how learners feel in class from a within-individual point of view. Q methodology can hopefully be capable of representing the dynamicity and complexity of the affective variables language learners experience in the interactive network of classroom learning. Thus, it is expected that innovative research methods such as the Q methodology be employed significantly more than before in the dynamic phase of SLA research in the upcoming years. (shrink)

This chapter distinguishes between two concepts of moral responsibility. We are responsible for our actions in the first sense only when those actions reflect our identities as moral agents, i.e. when they are attributable to us. We are responsible in the second sense when it is appropriate for others to enforce certain expectations and demands on those actions, i.e. to hold us accountable for them. This distinction allows for an account of moral responsibility for implicit bias, defended here, on which (...) people may lack attributability for actions caused by implicit bias but are still accountable for them. What this amounts to is leaving aside appraisal-based forms of moral criticism such as blame and punishment in favor of non-appraising forms of accountability. This account not only does more justice to our moral experience and agency, but will also lead to more effective practices for combating the harms of implicit bias. (shrink)

Young children judge that violations of ordinary, causal constraints are impossible. Yet children’s religious beliefs typically include the assumption that such violations can occur via divine agency in the form of miracles. We conducted two studies to examine this potential conflict. In Study 1, we invited 5- and 6-year-old Colombian children attending either a secular or a religious school to judge what is and is not possible. Children made their judgments either following a minimal prompt or following a reminder of (...) God’s extraordinary powers. Irrespective of their education, and whether or not they had been reminded of God’s extraordinary powers, children systematically judged violations of ordinary, causal constraints to be impossible. In Study 2, we asked if more extensive reminders of God’s special powers would prompt religious children to say that the impossible can happen. Five- and 6-year-old Colombian children attending either a secular or a religious school were presented with narratives in which the protagonist desired an ordinarily impossible outcome. In half the stories, the protagonist prayed to God for the desired outcome. Irrespective of education and of whether the protagonist prayed, children systematically concluded that the desired outcome would not occur and justified that conclusion by reference to ordinary causal constraints. Nevertheless, in a minority of their replies children did assert that violations of ordinary causality are possible. Overall, irrespective of their religious education, young children judge that events rarely deviate from their natural course; only occasionally do they acknowledge exceptions. (shrink)

The virtual brand community has become an important marketing tool for companies. A successful brand community marketing strategy should attract a large number of consumers. Although past studies have revealed consumer motivations for participating in virtual brand communities, they fail to answer an important question: Why is it so easy for some virtual brand communities to attract users while others have such difficulty? In this study, product characteristics are hypothesized to be important factors that determine consumer motivation to participate in (...) brand communities. Product characteristics can directly affect how actively consumers participate in brand communities. The results of questionnaires show that product complexity, product symbolism, and product satisfaction have a positive influence on consumers’ willingness to participate in brand communities. Notably, the duration of product use has a regulating effect on the influence of product satisfaction and product symbolism. A long period of product use weakens the influence of product satisfaction on consumers’ willingness to participate in brand communities. On the contrary, a long period of product use strengthens the influence of product symbolism on consumers’ willingness to participate in brand communities. This study enriches the literature on brand community participation and has implications for companies that aim to utilize brand communities for marketing. (shrink)

Quantum cognition research applies abstract, mathematical principles of quantum theory to inquiries in cognitive science. It differs fundamentally from alternative speculations about quantum brain processes. This topic presents new developments within this research program. In the introduction to this topic, we try to answer three questions: Why apply quantum concepts to human cognition? How is quantum cognitive modeling different from traditional cognitive modeling? What cognitive processes have been modeled using a quantum account? In addition, a brief introduction to quantum probability (...) theory and a concrete example is provided to illustrate how a quantum cognitive model can be developed to explain paradoxical empirical findings in psychological literature.

I defend an account of moral responsibility for implicit bias that is sensitive to both normative and pragmatic constraints: an acceptable theory of moral responsibility must not only do justice to our moral experience and agency, but also issue directives that are psychologically effective in bringing about positive changes in judgment and behavior. I begin by offering a conceptual genealogy of two different concepts of moral responsibility that arise from two distinct sources of philosophical concerns. We are morally responsible for (...) our actions in first sense only when those actions reflect our identities as moral agents—that is, when they are attributable to us as manifestations of our character, attitudes, ends, commitments, or values. On the other hand, we are responsible in the second sense when it is appropriate for others to enforce certain demands and expectations on those actions—in other words, to hold us accountable for them. I argue that we may sometimes lack attributability for actions caused by implicit bias, but that even then we are still accountable for them. Next, I expand beyond individual actions at a particular time to patterns of action across time, to consider what we can reasonably be expected to do when it comes to avoiding and eliminating implicit bias in our selves. By thinking of these expectations as grounded in imperfect duties, I show, we can expand our moral repertoire to include non-appraising critical moral responses, in addition to appraisal-based responses such as blame and punishment. Finally, I move beyond the actions of individuals to address the question of responsibility for eliminating the social conditions that breed implicit biases in the first place. I argue that accountability requires us not only to conform to a system of demands and expectations, but also to collectively organize to reform the system itself. By elaborating these multiple dimensions of moral responsibility—attributability versus accountability, particular versus patterns of action, individual versus collective—I demonstrate that the project of developing better practices of moral responsibility is continuous with, and thus contributes to, larger struggles for social equality and justice.

Question order effects are commonly observed in self-report measures of judgment and attitude. This article develops a quantum question order model (the QQ model) to account for four types of question order effects observed in literature. First, the postulates of the QQ model are presented. Second, an a priori, parameter-free, and precise prediction, called the QQ equality, is derived from these mathematical principles, and six empirical data sets are used to test the prediction. Third, a new index is derived from (...) the model to measure similarity between questions. Fourth, we show that in contrast to the QQ model, Bayesian and Markov models do not generally satisfy the QQ equality and thus cannot account for the reported empirical data that support this equality. Finally, we describe the conditions under which order effects are predicted to occur, and we review a broader range of findings that are encompassed by these very same quantum principles. We conclude that quantum probability theory, initially invented to explain order effects on measurements in physics, appears to be a powerful natural explanation for order effects of self-report measures in social and behavioral sciences, too.

This study used bibliometric data from Language Testing, a prestigious international peer-reviewed journal in the language testing field, to investigate research trends and development patterns in language testing. The bibliometric information included the number of publications, the most frequently researched test types and topics, the most cited publications and authors, the most prolific countries/regions and institutions and the most frequently collaborating countries/regions. The results showed that interest in language testing has increased over time and that regional tests and international tests (...) have been major concerns, while classroom tests/assessments have received less attention. Research topics were wide-ranging and addressed almost all language testing related issues, among which validity/validation received the highest interest across periods. Moreover, the publications were produced by a wide range of countries/regions and institutions and included collaborative research spanning various institutions and regions, although collaborative publications across countries were relatively scarce. Based on the findings of this study, implications and suggestions have been highlighted for future research, academic agencies and this journal. (shrink)
