Industry reputation crises trigger producers and consumers to switch to certification as a signal of quality, especially in a weak institutional environment. In this paper, we posit that firm certification as a signaling mechanism involves the co-evolution of firms and consumers. We investigate the impact of industry reputation crises on firm certification as a response strategy. Feedback between producers and consumers causes producers to seek more certifications over time to differentiate themselves from competitors. However, the proliferation of certifications may dilute (...) their credibility and reduce the effectiveness of the signal. Competition from imports that command higher trust from consumers exacerbates the problem in developing countries. We conduct empirical tests using firms in China’s dairy industry after an industry reputation crisis. The findings support our hypotheses. This study provides insights on the certification mechanisms through which producers and consumers interact and the effect of institutional environments on this interaction. It also offers implications for managers on how to better respond to industry crises and for policymakers on how to manage the certification market. (shrink)

This study investigates the influence of old directors on corporate social responsibility (CSR) using roughly 25,000 firm-year observations from 2001 to 2015 in the United States. We employ the widely used selection, optimization, and compensation (SOC) model from psychology to explain the CSR decisions of old directors. Our results indicate that firms with a higher percentage of old directors tend to have lower engagement in CSR activities. To address endogeneity, we adopt the difference-in-differences method and use the event of sudden (...) deaths and unexpected retirements of old directors and find that our results remain robust. Our analysis also reveals that the negative impact of old directors on CSR is more significant in firms where directors receive fewer reputational spillover benefits from CSR initiatives and/or firms exhibiting poor corporate governance. In addition, this adverse impact of old directors comes from two effects: a reduction in efforts to enhance CSR strengths and an increase in inaction to address CSR concerns. Overall, these findings suggest that the CSR decision-making process of old directors involves assessing the costs and benefits of CSR engagements, consistent with our hypothesis derived from the SOC model.

Arbuscular mycorrhizal fungi are considered as a potential biotechnological tool for improving phytostabilization efficiency and plant tolerance to heavy metal-contaminated soils. However, the mechanisms through which AMF help to alleviate metal toxicity in plants are still poorly understood. A greenhouse experiment was conducted to evaluate the effects of two AMF species on the growth, Pb accumulation, photosynthesis and antioxidant enzyme activities of a leguminous tree at Pb addition levels of 0, 500, 1000 and 2000 mg kg-1 soil. AMF symbiosis decreased (...) Pb concentrations in the leaves and promoted the accumulation of biomass as well as photosynthetic pigment contents. Mycorrhizal plants had higher gas exchange capacity, non-photochemistry efficiency, and photochemistry efficiency compared with non-mycorrhizal plants. The enzymatic activities of superoxide dismutase, ascorbate peroxidases and glutathione peroxidase were enhanced, and hydrogen peroxide and malondialdehyde contents were reduced in mycorrhizal plants. These findings suggested that AMF symbiosis could protect plants by alleviating cellular oxidative damage in response to Pb stress. Furthermore, mycorrhizal dependency on plants increased with increasing Pb stress levels, indicating that AMF inoculation likely played a more important role in plant Pb tolerance in heavily contaminated soils. Overall, both F. mosseae and R. intraradices were able to maintain efficient symbiosis with R. pseudoacacia in Pb polluted soils. AMF symbiosis can improve photosynthesis and reactive oxygen species scavenging capabilities and decrease Pb concentrations in leaves to alleviate Pb toxicity in R. pseudoacacia. Our results suggest that the application of the two AMF species associated with R. pseudoacacia could be a promising strategy for enhancing the phytostabilization efficiency of Pb contaminated soils.

Antibiotic resistance in bacteria has become a great threat to global public health. Tigecycline is a next‐generation tetracycline that is the final line of defense against severe infections by pan‐drug‐resistant bacterial pathogens. Unfortunately, this last‐resort antibiotic has been challenged by the recent emergence of the mobile Tet(X) orthologs that can confer high‐level tigecycline resistance. As it is reviewed here, these novel tetracycline destructases represent a growing threat to the next‐generation tetracyclines, and a basic framework for understanding the molecular epidemiology and (...) resistance mechanisms of them is presented. However, further large‐scale epidemiological and functional studies are urgently needed to better understand the prevalence and dissemination of these newly discovered Tet(X) orthologs among Gram‐negative bacteria in both human and veterinary medicine.

Monetary intelligence theory asserts that individuals apply their money attitude to frame critical concerns in the context and strategically select certain options to achieve financial goals and ultimate happiness. This study explores the dark side of monetary Intelligence and behavioral economics—dishonesty. Dishonesty, a risky prospect, involves cost–benefit analysis of self-interest. We frame good or bad barrels in the environmental context as a proxy of high or low probability of getting caught for dishonesty, respectively. We theorize: The magnitude and intensity of (...) the relationship between love of money and dishonest prospect may reveal how individuals frame dishonesty in the context of two levels of subjective norm—perceived corporate ethical values at the micro-level and Corruption Perceptions Index at the macro-level, collected from multiple sources. Based on 6382 managers in 31 geopolitical entities across six continents, our cross-level three-way interaction effect illustrates: As expected, managers in good barrels, mixed barrels, and bad barrels display low, medium, and high magnitude of dishonesty, respectively. With high CEV, the intensity is the same across cultures. With low CEV, the intensity of dishonesty is the highest in high CPI entities —the Enron Effect, but the lowest in low CPI entities. CPI has a strong impact on the magnitude of dishonesty, whereas CEV has a strong impact on the intensity of dishonesty. We demonstrate dishonesty in light of monetary values and two frames of social norm, revealing critical implications to the field of behavioral economics and business ethics. (shrink)

Monetary Intelligence theory asserts that individuals apply their money attitude to frame critical concerns in the context and strategically select certain options to achieve financial goals and ultimate happiness. This study explores the bright side of Monetary Intelligence and behavioral economics, frames money attitude in the context of pay and life satisfaction, and controls money at the macro-level and micro-level. We theorize: Managers with low love of money motive but high stewardship behavior will have high subjective well-being: pay satisfaction and (...) quality of life. Data collected from 6586 managers in 32 cultures across six continents support our theory. Interestingly, GDP per capita is related to life satisfaction, but not to pay satisfaction. Individual income is related to both life and pay satisfaction. Neither GDP nor income is related to Happiness. Our theoretical model across three GDP groups offers new discoveries: In high GDP entities, “high income” not only reduces aspirations—“Rich, Motivator, and Power,” but also promotes stewardship behavior—“Budget, Give/Donate, and Contribute” and appreciation of “Achievement.” After controlling income, we demonstrate the bright side of Monetary Intelligence: Low love of money motive but high stewardship behavior define Monetary Intelligence. “Good apples enjoy good quality of life in good barrels.” This notion adds another explanation to managers’ low magnitude of dishonesty in entities with high Corruption Perceptions Index. In low GDP entities, high income is related to poor Budgeting skills and escalated Happiness. These managers experience equal satisfaction with pay and life. We add a new vocabulary to the conversation of monetary intelligence, income, GDP, happiness, subjective well-being, good and bad apples and barrels, corruption, and behavioral ethics. (shrink)

Action video game (AVG) has attracted increasing attention from both the public and from researchers. More and more studies found video game training improved a variety of cognitive functions. However, it remains controversial whether healthy adults can benefit from AVG training, and whether young and older adults benefit similarly from AVG training. In the present study, we aimed to quantitatively assess the AVG training effect on the cognitive ability of adults and to compare the training effects on young and older (...) adults by conducting a meta-analysis on previous findings. We systematically searched video game training studies published between January 1986 and July 2015. Twenty studies were included in the present meta-analysis, for a total of 313 participants included in the training group and 323 participants in the control group. The results demonstrate that healthy adults achieve moderate benefit from AVG training in overall cognitive ability and moderate to small benefit in specific cognitive domains. In contrast, young adults gain more benefits from AVG training than older adults in both overall cognition and specific cognitive domains. Age, education, and some methodological factors, such as the session duration, session number, total training duration, and control group type, modulated the training effects. These meta-analytic findings provide evidence that AVG training may serve as an efficient way to improve the cognitive performance of healthy adults. We also discussed several directions for future AVG training studies. (shrink)

Objectives: The corona virus disease-2019 pandemic spread globally, and we aimed to investigate the psychosocial impact on healthcare workers in China during the pandemic.Methods: In this systematic review and meta-analysis, we searched seven electronic databases for cross-sectional studies on psychosocial impact on HWs in relation to COVID-19 from January 1, 2020 to October 7, 2020. We included primary studies involving Chinese HWs during the pandemic, and data were extracted from the published articles. Our primary outcome was prevalence of anxiety, depression, (...) and stress disorders. We pooled prevalence value with their 95% confidence interval using random effect models and assessed study quality on the basis of an 11-item checklist recommended by the Agency for Healthcare Research and Quality. The study protocol was registered in PROSPERO.Results: We identified 25 articles comprising a total of 30,841 completed questionnaires and 22 studies for meta-analysis. The prevalence of anxiety, depression, and stress disorders was 34.4%, 31.1%, and 29.1% for HWs. The pooled prevalence of anxiety disorders for HWs from late January to early February was 46.4%, significantly higher than those in mid-term February and after late February. The pooled prevalence of depression disorders for HWs from late January to early February was 46.5%, significantly higher than those in mid-term February and after late February. HWs working in Hubei Province had a higher prevalence of anxiety and a lower prevalence of depression than those working in other regions. Nurses had a higher prevalence of anxiety and depression than other HWs.Conclusions: About one-third of HWs in China suffered anxiety, depression, and stress at the early epidemic of COVID-19. HWs in Hubei Province, especially nurses, had a higher prevalence of psychological disorders. During the pandemic, a negative psychological state may persist in a proportion of Chinese HWs, fluctuating with the control of the pandemic. The long-term impact should continue to be observed. Attention should be paid to HWs for their psychological impact due to the pandemic.Systematic Review Registration: The study protocol was registered with PROSPERO. (shrink)

Like other sciences, biosemiotics also has its time-honoured archive, consisting, among other things, of writings by those who have been invented and revered as ancestors of the discipline. One such example is Jakob von Uexküll who has been hailed as a precursor of semiotics, developing his theory of “sign” and “meaning” independently of Saussure and Peirce. The juxtaposition of “sign” and “meaning” is revelatory because one can equally legitimately claim Uexküll as a hermeneutician in the same way as others having (...) claimed him as a semiotician. Such a novel temptation can be justified by Uexküll’s prolonged obsession with Sinn and Bedeutung since his first book in 1909. This paper attempts to reconstruct the immediate intellectual horizon of Uexküll’s historicity, a discursive space traversed by his contemporaries Frege and Husserl, in order to see how Uexküll’s discussions of Zeichen and Gegenstand, Sinn and Bedeutung, were informedby other philosophers of language, and to establish Uexküll as a phenomenological hermeneutician in the tradition of Husserl, Heidegger and Gadamer. To forestall and counter possible criticism that hermeneutics is primarily concerned with textual interpretation, while Uexküll is at most an interpreter of animal life, the paper will discuss his unfinished parody of the Platonic dialogue Meno, which is entitled Die ewige Frage: Biologische Variationen über einen platonischen Dialog (1943). It is through such textual practice that one witnesses the emergence of an Uexküll who embodies at once the addressee exercising his understanding of ancient texts as well as the second addresser recoding his explanation to another group of targeted addressees. This textual practice already goes beyond the confines of biology and in fact involves the linguistic pragmatics of rhetoric and speech act. (shrink)

Juri Lotman’s well-known distinction of primary modeling system versus secondary modeling system is a lasting legacy of his that has been adhered to, modified, and refuted by semioticians of culture and nature. Adherence aside, modifications and refutations have focused on the issue whether or not language is a primary modeling system, and, if not, what alternatives can be made available to replace it. As Sebeok would concur, for both biosemiosis and anthroposemiosis, language can only be a secondary modeling system on (...) top of the biological experience of Umwelt or human sensory system. This paper proposes to explore the possibility of a “preverbal” modeling system suggested by Lotman’s spatial concept of semiosphere, and discuss its implications in cross-cultural dialogue.

As one of the foundations of existential positive psychology, self-transcendence can bring positive intrapersonal and interpersonal outcomes, especially in the COVID-19 era in which people are suffering huge mental stress. Based on Schwartz's theory of human basic values, the current study combines variable-centered and person-centered approaches to examine the relationships between adolescents' values and mental health across two regions in China. The results generally showed that both self-enhancement and conservation values were positively correlated with depression and loneliness, while both self-transcendence (...) and openness to change values negatively correlated with depression and loneliness. The results also showed that there were four value clusters, and, compared to adolescents in the self-focus and undifferentiated values cluster, all adolescents in the anxiety-free values cluster reported lower depression and loneliness, while all adolescents in the other-focus values cluster reported higher depression and loneliness. The differences between the two regional groups only emerged in depression. Specifically, adolescents in Shanghai have higher levels of depression than adolescents in Qingdao. This study provides some evidence for the new science of self-transcendence among adolescents and also sheds light on how we may improve the level of mental health during the COVID-19 era. (shrink)

The study of natural disaster and its discursive dimensions from a semiotic perspective can provide a theoretical frame for the scientific communication of global catastrophes. In this paper I will suggest two models; one is a semiotic model on the natural catastrophic events and the other is a hexagon model composed of semiotic dimensions of natural disaster discourse. The six main modules include narration, description, explication, visualization, prevention, and recovery action.

When ancient Chinese philosophy culminated in the sixth to third centuries BCE, “hundreds of flowers [intellectual schools] were blooming”, yet not many theoreticians were particularly interested in questions regarding the relationship between animal and human life — despite their profuse discussion of, and heated debates about, both “nature” and “human nature” in their writings. This indifferent attitude towards creatures lower than humans is best illustrated by Confucius (551–479 BCE), who observed: “It is impossible to associate with birds and beasts, as (...) if they were the same as us.” Later, however, this condescending attitude of the Sage would be challenged by the Daoist philosopher Zhuangzi (370 to 301 BCE), who untiringly advocates the equity of all creatures in the universe — a place where both living and fabulous organisms cohabit and co-evolve with one another, as well as with their environments. Morever, even Confucius’s descendent Mencius (c.372–289 BCE) did not endorse his mentor’s position, for the latter’s own writings are likewise inhabited by all kinds of creatures which not only serve the passive role of poetic figuration, but actually also construct their respective Umwelten, paralleled by the umwelt-construction of human beings. Recent advances in biosemiotics and ecosemiotics have enabled us to reread some of these philosophical texts, and to shed new light on this obscure aspect of Chinese thinking. This paper will draw upon the sign reflections of C. S. Peirce (1839–1914) and Jakob von Uexküll (1864–1944), and make use of a composite analytical method of text semiotics and dialogue studies, to examine a number of political and ethical allegories by Zhuangzi and Mencius. Acknowledging the necessarycircularity of interpretation and the homogeneity of observer and observed, the essay explores the ways in which ancient philosophical texts can be made compatible with contemporary biological and semiotic thinking.

For all his profound interest in Secondness and its manifestation in various kinds of indices, including deictics, Peirce rarely addresses the inter-pronominalrelationships. Whilst the American founder of semiotics would designate language as a whole to Thirdness, only within the larger framework of which deictics can work, the German philosopher Cassirer observes that “what characterizes the very first spatial terms that we find in language is their embracing of a defi nite ‘deictic’ function”. For Cassirer the significance of pronominals, especially the (...) I-Thou relationship, lies in its impact on the development of spatial concept that lays the foundation of symbolic forms. It may look strange why the “designatives” of I, Thou, He, in Peirce’s own terms, so obvious in their categorial and empirical differentiation, should fail to be reduceable to the triad of Firstness, Secondness, and Thirdness. It is interesting, however, that in his 1906 correspondence with Lady Welby, Peirce should refer to the strange “Communicational Interpretant”, or “the Cominterpretant, which is a determination of that mind into which the minds of utterer and interpreter have to be fused in order that any communication should take place”. Peirce asserts that this communication of a Form, say, being in love, is made possible by sign. This paper discusses Peirce’s and Cassirer’s references to deictics or indexical sign, in particular, inter-personal relationships, in light of Benveniste’s concept of discourse, and probes into a possible subtext underlying the Peirce-Welby correspondence.

Naming, according to Sebeok, constihttes the first stage of zoosemiotics. This special but common use of language acrually inaugurates more complicated procedures of human discourse on non-human kingdom, including classification of its members. Because of language's double articulation in sound and sense, as well as the grapheme's pleremic (meaning-full) rather than cenemic (meaning-empty) characteristic (according to Hjelmslev). Chinese script is capable of naming and grouping animals randomly but effectively. This paper attempts to describe the said scriptorial "necessity of naming" (Kripke) (...) in classical Chinese by citing all the creatures, real or fabulous, with a /ma/ (horse) radical. (shrink)

In traditional Chinese literary criticism, textual strategies comparable to intertextuality have governed Chinese critics’ and poets’ reading and writing aboutliterature throughout the dynasties. Drawing on the intertextual theories of Kristeva and Riffaterre, the paper probes into the phenomenon of sign system-mutations in two highly influential ancient texts: the Confucian Classic of Changes of the fifth century B.C.E. and Liu Xie’s The Literary Mind and the Carving of Dragons, an ars poetica in the third century. The transformation of sign systems from (...) nonverbal to verbal, in the case of the Changes, and from literate to literary or “creative” to “theoretical”, in the case of the Dragons, bears witness to the Hjelmslevian reciprocity of object-semiotic and meta-semiotic.

The metaphor of parasites or parasitism has dominated literary critical discourse since the 1970s, prominent examples being Michel Serres in France and J. Hillis Miller in America. In their writings the relationship between text and paratext, literature and criticism, is often likened to that between host and parasite, and can be therefore deconstructed. Their writings, along with those by Derrida, Barthes, and Thom, seem to be suggesting the possibility of a semiotics of parasitism. Unfortunately, none of these writers has drawn (...) enough on the biological foundation of parasitism. Curiously, even in biology, parasitism is already a metaphor through which the signified of an ecological phenomenon involving two organisms is expressed by the signifier of “[eating] food at another’s [side] table”. This paper will make some preliminary remarks on semiotics of parasitism, based on the notions of Umwelt (Jakob von Uexküll) and structural coupling (Maturana and Varela). It will look into the phenomenon of co-evolutionary process in community ecology. With reference to empirical history, the project will briefly surveythe literary and medical praxis of the 17th century England where large number of creative writings referred to the phenomenon of parasitism, which was deeply embedded in religious practice (e.g., the Eucharist) and political life (e.g., the courtier ecology in monarchy) of the times. Finally, it will touch upon the possible ‘parasitic’ relationship between language and biology. (shrink)

In his well-known essay, ‘What Is a Sign?’ (CP 2.281, 285) Peirce uses ‘likeness’ and ‘resemblance’ interchangeably in his definition of icon. The synonymity of the two words has rarely, if ever, been questioned. Curiously, a locus classicus of the pair, at least in F. M. Cornford’s English translation, can be found in a late dialogue of Plato, namely, the Sophist. In this dialogue on the myth and truth of the sophists’ profession, the mysterious ‘stranger’, who is most likely Socrates’ (...) persona, makes the famous distinction between eikon (likeness) and phantasma (semblance) (236a,b). For all his broad knowledge in ancient philosophy, Peirce never mentioned this parallel; nor has any Peircean scholar identified it. There seems to be little problem with eikon as likeness, but phantasma may give rise to a puzzle which this paper will attempt to solve. Plato uses two pairs of words: what eikon is to phantasma is eikastikén (the making of likeness [235d]) to phantastikén (semblance making [236c]). In other words, icons come into being because of the act of icon-making, which is none other than indexicality. Witness what Peirce says about the relationship between photographs and the objects they represent: “But this resemblance is due to the photographs having been produced under such circumstances that they were physically forced to correspond point by point to nature.” (Ibid.) Thus the iconicity which links the representamen (sign) and its object is made possible not only by an interpretant, but also by idexisation. Their possible etymological and epistemological links aside, the Peircean example of photographing and the Platonic discussion of painting and sculpturing in the Sophist, clearly show the physio-pragmatic aspect of iconicity. The paper will therefore reread the Peircean iconicity by closely analysing this relatively obscure Platonic text, and by so doing restore to the text its hidden semiotic dimension. (shrink)

The spread of epidemics, especially COVID-19, is having a significant impact on the world. If an epidemic is not properly controlled at the beginning, it is likely to spread rapidly and widely through the coexistence relationship between natural and social systems. A university community is a special, micro-self-organized social system that is densely populated. However, university authorities in such an environment seem to be less cautious in the defence of an epidemic. Currently, there is almost no quantitative research on epidemic (...) spreading and response strategies in universities. In this paper, a case study of a university community is considered for a simulation of an infection evolving after an epidemic outbreak based on the method of system dynamics of the three stages. The results show the following: By improving the speed of the initial emergency response, the total number of patients can be effectively controlled. A quarantine policy helps to slow down the evolution of infection. The higher the isolation ratio, the higher the cost; therefore, the isolation ratio should be optimized. It is important to make emergency plans for controlling epidemic spreading and carry out emergency drills and assessments regularly. According to the results of this study, we suggest an emergency management framework for public health events in university communities. (shrink)

RNA editing is a major post-transcriptional mechanism that changes specific nucleotides at the RNA level. The most common RNA editing type in humans is adenosine to inosine editing, which is mediated by ADAR enzymes. RNA editing events can not only change amino acids in proteins, but also affect the functions of non-coding RNAs such as miRNAs. Recent studies have characterized thousands of miRNA RNA editing events across different cancer types. Importantly, individual cases of miRNA editing have been reported to play (...) a role in cancer development. In this review, we summarize the current knowledge of miRNA editing in cancer, and discuss the mechanisms on how miRNA-related editing events modulate the initiation and progression of human cancer. Finally, we discuss the challenges and future directions of studying miRNA editing in cancer. RNA editing is introduced by ADAR or APOBEC enzymes, leading to specific nucleotide changes, respectively. The interplays between RNA editing and miRNAs may play important roles in cancer. This graphical abstract shows four major mechanisms through which miRNAs interact with RNA editing to confer a functional impact on tumor development. (shrink)

In real life, listening to music may be associated with an eyes-closed or eyes-open state. The effect of eye state on listeners’ reaction to music has attracted some attention, but its influence on brain activity has not been fully investigated. The present study aimed to evaluate the electroencephalographic (EEG) markers for the emotional valence of music in different eye states. Thirty participants listened to musical excerpts with different emotional content in the eyes-closed and eyes-open states. The results showed that participants (...) rated the music as more pleasant or with more positive valence under an eyes-open state. In addition, we found that the alpha asymmetry indices calculated on the parietal and temporal sites reflected emotion valence in the eyes-closed and eyes-open states, respectively. The theta power in the frontal area significantly increased while listening to emotional-positive music compared to emotional-negative music under the eyes-closed condition. These effects of eye states on EEG markers are discussed in terms of brain mechanisms underlying attention and emotion. (shrink)

Like other sciences, biosemiotics also has its time-honoured archive, consisting of writings by those who have been invented and revered as ancestors of the discipline. One such example is Jakob von Uexküll. As to the people who ‘invented’ him, they are either, to paraphrase a French cliché, ‘agents du cosmopolitisme sémiotique’ like Thomas Sebeok, or de jure and de facto progenitor like Thure von Uexküll. In the archive is the special issue of Semiotica 42. 1 (1982) edited by the late (...) Sebeok and introduced by Thure von Uexküll. It is in the opening essay that Thure von UexküIl tries to restore Jakob von Uexküll’s role as a precursor of semiotics by negotiating the Elder with Saussure and the linguistics-oriented ‘semiology’ in his wake. However, semiotic mapping, in the strictly ‘disciplinary’ sense, of Jakob von Uexküll is no easy task because he ‘knew neither Peirce nor Saussure and did not use their terminology’ (Thure von Uexküll 1982,2). Because Thure prefers to call the Elder’s science ‘general semiotics’ (Thure von Uexküll 1982), this paper begins by assessing Thure von Uexküll’s semiotic configuration of Jakob, probe into the force and limits of the linguistic analogy, revisit the already time-honoured debate on the primary and secondary modelling systems, which was made famous by the Moscow-Tartu semioticians in the early 1970s, but severely criticized by Sebeok and his followers. The paper engages Sebeok from several fronts, directed first at his relegation of the Saussurian linguistic model, then at his critique of the Primary Modelling System, and finally at his reservation about evolutionism in light of the current debate on gene/meme co-evolution.

According to the dual-system theories, the decisions in an ultimatum game are governed by the automatic System 1 and the controlled System 2. The former drives the preference for fairness, whereas the latter drives the self-interest motive. However, the association between the contributions of the two systems in UG and the cognitive process needs more direct evidence. In the present study, we used the process dissociation procedure to estimate the contributions of the two systems and recorded participants eye movements to (...) examine the cognitive processes underlying UG decisions. Results showed that the estimated contributions of the two systems are uncorrelated and that they demonstrate a dissociated pattern of associations with third variables, such as reaction time and mean fixation duration. Furthermore, the relative time advantage and the transitions between the two payoffs can predict the final UG decisions. Our findings provide evidence for the independent contributions of preference for fairness and self-interest maximizing inclinations to UG and shed light on the underlying processes. (shrink)

ObjectiveLeveraging an integrative multimodal MRI paradigm to elaborate on the hippocampus-derived structural and functional changes in children and adolescents with juvenile idiopathic arthritis and to explore potential correlations within the “joint-inflammation-brain” axis during the period of central neural system development.MethodsTwenty-one patients with JIA all completed the multimodal MRI scanning, laboratory tests, and neuropsychological assessments; meanwhile, 23 matched controls were recruited. We then harnessed the spherical harmonics with a point distribution model and the ROI-to-voxel functional connectivity to measure the hippocampal shape (...) and hippocampo-cortical FC patterns. Correlation analysis was performed to explore the potential links in neuroimaging features with disease-related indices.ResultsCompared to controls, JIA patients only presented an atrophic tendency in the posterior part of the bilateral hippocampus. The hippocampo-cortical FC revealed the between-group divergences mainly located at the pain matrix, striatum, and temporal lobe. Remarkably, the enhanced FC between the right hippocampus and postcentral cortex is positively correlated with the disability index, while the weakened FC of right anterior hippocampus with right insula and that of left posterior hippocampus with left superior temporal gyrus was inversely related to the erythrocyte sedimentation rate and anxiety status, separately.ConclusionAs with macroscopic damages, the altered functional-connectome patterns of the hippocampus in JIA patients might be more sensitive to detect the early neuropathological changes. Moreover, the functional disturbances were demonstrated associated with the physical disability, inflammation, and emotional status. These findings may enlighten us on the underlying neuropathological mechanism of CNS comorbidities in JIA. (shrink)

Attending cram school has long been a trend in ethnic Chinese culture areas, including Taiwan. Despite the fact that school reform policies have been implemented in Taiwan, cram schools have continued to prosper. Therefore, in this educational culture, how to achieve a good educational effect is also a topic worthy of discussion. However, whether students really engage in those tutoring programs provided by cram schools has seldom been studied. To address this gap, this study explored how parents’ hovering attitude toward (...) life and coursework influences their children’s engagement in cram schools. This study targeted those students who attend English cram schools to test the correlates between two types of helicopter parenting, tutoring engagement and continued attendance at cram schools. A total of 320 questionnaires were sent out, and 300 were returned, giving an overall response rate of 93.75%. Excluding seven incomplete or invalid questionnaires, 293 valid questionnaires were received. The results of this study show that hovering behavior awareness is negatively related to cram school engagement, whereas cram school engagement is positively related to the intention to continue attending cram school. Moreover, the results imply that parents should alleviate their helicoptering behavior to enhance their children’s engagement in cram school tutoring programs. (shrink)
