The global spread of the novel coronavirus is affected by the spread of related misinformation—the so-called COVID-19 Infodemic—that makes populations more vulnerable to the disease through resistance to mitigation efforts. Here, we analyze the prevalence and diffusion of links to low-credibility content about the pandemic across two major social media platforms, Twitter and Facebook. We characterize cross-platform similarities and differences in popular sources, diffusion patterns, influencers, coordination, and automation. Comparing the two platforms, we find divergence among the prevalence of popular (...) low-credibility sources and suspicious videos. A minority of accounts and pages exert a strong influence on each platform. These misinformation “superspreaders” are often associated with the low-credibility sources and tend to be verified by the platforms. On both platforms, there is evidence of coordinated sharing of Infodemic content. The overt nature of this manipulation points to the need for societal-level solutions in addition to mitigation strategies within the platforms. However, we highlight limits imposed by inconsistent data-access policies on our capability to study harmful manipulations of information ecosystems. (shrink)

Objective wealth plays an important role in social interaction and economic decision making. Previous studies indicate that objective wealth of others may influence the way we participate in resources allocation. However, the effect of objective wealth on responses to fairness-related resource distribution is far from clear, as are the underlying neural processes. To address this issue, we dynamically manipulated proposers’ objective wealth and analyzed participants’ behavior as responders in a modified Ultimatum Game, during which event-related potentials were recorded. Behavioral results (...) showed that participants were prone to reject unfair proposals although that rejection would reduce their own benefit. Importantly, participants were more likely to accept unfair offers from proposers with low objective wealth than from proposers with high objective wealth, with a drastic increase in acceptance rates of unfair offers from 32.79 to 50.59%. Further electrophysiological results showed that there was significantly enhanced feedback-related negativity amplitude toward proposers with high objective wealth for unfair offers. Furthermore, the late frontal negativity amplitude was larger for all the conditions which are not high-fair, which might be the only option that did not elicit any ambiguity. These findings suggest a strong role of proposers’ objective wealth in modulating responders’ behavioral and neural responses to fairness. (shrink)

The emergence of new biological traits is landmarks of evolutionary progress. However, when, how, and why do they appear? We propose a universal mechanism, a Buffering Mechanism of Evolution to understand these questions. We speculate that all organisms possess this potential buffer capacity. This capacity would be triggered by the pressures, natural or artificial, to express the intrinsic potential variants. The potential buffer capacity of the organism increases for further selections as evolutionary progress occurs. The higher the evolutionary level of (...) the organism, the greater the potential buffer capacity, and importantly, the buffer capacity versus the pressures of selections will result. However, when the pressures are far more than the potential capacity of the targets, the natural or artificial pressures then compromise the genetic buffering system resulting in possible species extinction if the emergence of new traits fails.

This study draws on a synergy of Corpus Linguistics and Critical Discourse Studies to scrutinize the portrayal of hackers in China Daily and The New York Times in the 21st century, primarily revolving around the main social actors and targets in hacking. This study demonstrates that both media share a positive transformation of the image-building of hackers in the 21st century. Besides, countries are salient social actors in hacker media discourse and the two media differ in their ways of constructing (...) them. The New York Times tends to have a negative other-representation and categorical otherness of specific countries through such discursive strategies as negative other-representation and group categorization, whereas China Daily is prone to insist on opposing the US hacking allegations in a defensive manner. Regarding major targets, China Daily highlights government websites whereas The New York Times emphasizes government websites, officials’ emails, large technology companies, and election infrastructure. The analysis shows that the two media’s different ways of framing hackers are underpinned by the ideologies behind them and the Chinese and US socio-political landscapes. This study can provide insights into how hacker discourse in media is represented in the 21st century and how national identities are constructed in the media representations of hackers. (shrink)

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

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

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

AimResting state functional magnetic resonance imaging was used to analyze changes in functional connectivity within various brain networks and functional network connectivity among various brain regions in patients with high myopia.Methodsrs-fMRI was used to scan 82 patients with HM and 59 healthy control volunteers matched for age, sex, and education level. Fourteen resting state networks were extracted, of which 11 were positive. Then, the FCs and FNCs of RSNs in HM patients were examined by independent component analysis.ResultsCompared with the HC (...) group, FC in visual network 1, dorsal attention network, auditory network 2, visual network 3, and sensorimotor network significantly increased in the HM group. FC in default mode network 1 significantly decreased. Furthermore, some brain regions in default mode network 2, default mode network 3, auditory network 1, executive control network, and significance network increased while others decreased. FNC analysis also showed that the network connection between the default mode network and cerebellar network was enhanced in the HM group.ConclusionCompared with HCs, HM patients showed neural activity dysfunction within and between specific brain networks, particularly in the DMN and CER. Thus, HM patients may have deficits in visual, cognitive, and motor balance functions. (shrink)

AimPatients with high myopia reportedly exhibit changes in functional brain activity, but the mechanism underlying such changes is unclear. This study was conducted to observe differences in dynamic spontaneous brain activity between patients with HM and healthy controls via dynamic regional homogeneity analysis.MethodsResting-state functional magnetic resonance imaging scans were performed on 82 patients with HM and 59 HCs who were closely matched for age, sex, and weight. The dReHo approach was used to assess local dynamic activity in the human brain. (...) The association between mean dReHo signal values and clinical symptoms in distinct brain areas in patients with HM was determined via correlation analysis.ResultsIn the left fusiform gyrus, right inferior temporal gyrus, right Rolandic operculum, right postcentral gyrus, and right precentral gyrus, dReHo values were significantly greater in patients with HM than in HCs.ConclusionPatients with HM have distinct functional changes in various brain regions that mainly include the L-FG, R-ITG, R-ROL, R-PoCG, and R-PreCG. These findings constitute important evidence for the roles of brain networks in the pathophysiological mechanisms of HM and may aid in the diagnosis of HM. (shrink)

PurposeTo study the changes in functional connections between the left and right hemispheres of patients with high myopia and healthy controls by resting functional magnetic resonance imaging based on voxel-mirrored homotopic connectivity. To study the changes in resting-state functional connectivity between the left and right hemispheres of patients with HM and healthy controls at rest by using resting functional magnetic resonance imaging based on voxel-mirror homotopy connectivity.Patients and MethodsA total of 89 patients with HM and 59 HCs were collected and (...) matched according to gender, age, and education level. The VMHC method was used to evaluate the changes in rsFC between cerebral hemispheres, and a correlation analysis was carried out to understand the differences in brain functional activities between the patients with HM and the HCs.ResultsCompared with the HCs, the VMHC values of the putamen and fusiform in the HM group were significantly lower.ConclusionThis study preliminarily confirmed the destruction of interhemispheric functional connection in some brain regions of the patients with HM and provided effective information for clarifying the neural mechanism of patients with HM.

A growing body of business ethics research has shown that firms are beginning to embrace the lesbian, gay, bisexual, and transgender (LGBT) community with internal organizational policies and temporary activism activities. Despite these positive developments, little research has examined firms’ LGBT inclusion strategy at the product level and whether adding LGBT representation to products helps, hurts, or has no impact on corporate products’ market performance. Prior studies have examined LGBT-themed and LGBT-vague representations and identified limitations of both. The current research (...) presents an alternative LGBT-inclusive representation in which heterosexual and LGBT imagery are both presented, with the former receiving more exposure than the latter. A secondary analysis of 4216 movies and a controlled experiment reveal converging evidence: movies with LGBT-inclusive representation outperform those with no LGBT representation or with LGBT-themed representation. The superiority of LGBT-inclusive representation comes from its ability to appeal to consumer segments holding favorable and unfavorable LGBT attitudes. While cultural and entertainment products often play profound roles in changing society’s ethical standards and moral attitudes, they are rarely studied in the business ethics literature. Our findings fill this gap while answering a multimillion-dollar question for the entertainment industry. (shrink)

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

Balancing self‐renewal and differentiation of stem cells is an important issue in stem cell and cancer biology. Recently, the Drosophila neuroblast (NB), neural stem cell has emerged as an excellent model for stem cell self‐renewal and tumorigenesis. It is of great interest to understand how defects in the asymmetric division of neural stem cells lead to tumor formation. Here, we review recent advances in asymmetric division and the self‐renewal control of Drosophila NBs. We summarize molecular mechanisms of asymmetric cell division (...) and discuss how the defects in asymmetric division lead to tumor formation. Gain‐of‐function or loss‐of‐function of various proteins in the asymmetric machinery can drive NB overgrowth and tumor formation. These proteins control either the asymmetric protein localization or mitotic spindle orientation of NBs. We also discuss other mechanisms of brain tumor suppression that are beyond the control of asymmetric division. (shrink)

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

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

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

Respect for patient autonomy is paramount in resolving ethical tensions in end-of-life care. The concept of relational autonomy has contributed to this debate; however, scholars often use this concept in a fragmented manner. This leads to partial answers on ascertaining patients’ true wishes, meaningfully engaging patients’ significant others, balancing interests among patients and significant others, and determining clinicians’ obligations to change patients’ unconventional convictions to enhance patient autonomy. A satisfactory solution based on relational autonomy must incorporate patients’ competence (apart from (...) decisional capacity), authenticity (their true desires or beliefs) and the involvement level of their significant others. To that end, we argue that John Christman’s procedural approach to relational autonomy provides critical insights, such as the diachronic or socio-historical personhood, sustained critical reflection and his recent explication of the nature of asymmetrical relationships and helpful interlocutors. This study reviews Christman’s account, proposes minor modifications and advocates for an integrated three-dimensional model for medical decision-making. Clarifying the relationship among the three elements promotes an ethical framework with a coherent understanding of relational autonomy. This model not only provides a descriptive and normative framework for end-of-life care practice but also reconsiders the nature of the clinician–patient relationship and its normative implications. We further present a case study to illustrate the merits of our proposed model. Altogether, our proposal will help navigate complex medical decision-making, foster trust and negotiate shared values between patients and their significant others, particularly in end-of-life care.

With the rapid development of information age, various social groups and corresponding institutions are producing a large amount of information data every day. For such huge data storage and identification, in order to manage such data more efficiently and reasonably, traditional semantic similarity algorithm emerges. However, the accuracy of the traditional semantic similarity algorithm is relatively low, and the convergence of corresponding algorithm is poor. Based on this problem, this paper starts with the conceptual structure of language, analyzes the depth (...) of language structure and the distance between nodes, and analyzes the two levels as the starting point. For the information of a specific data resource description frame type, the weight of interconnected edges is used for impact analysis so as to realize the semantic similarity impact analysis of all information data. Based on the above improvements, this paper also systematically establishes the data information modeling process based on language conceptual structure and establishes the corresponding model. In the experimental part, the improved algorithm is simulated and analyzed. The simulation results show that compared with the traditional algorithm, the algorithm has obvious accuracy improvement.

Background:Suicide remains an important cause of premature deaths and draws much media attention. However, unsafe reporting and portrayal of suicides by the media have been associated with increased risk of suicidal behavior. Current evidence suggests that media capacity-building could potentially prevent suicide. However, there are still knowledge gaps in terms of a lack of data on effective strategies for improving awareness and safe reporting of suicide-related media content. This study aims to investigate the effectiveness of a workshop conducted with members (...) of the media community on the safe reporting of suicide-related content.Methods:An interventional single-arm pre and post pilot study was conducted on a sample of the Malaysian media community recruited through purposive and snowball sampling. The media safe reporting workshop was conducted by a suicide prevention expert with a media industry background. Thirty participants completed a self-reported evaluation questionnaire on their awareness and knowledge of reporting on suicide-related media content; before and after the interventional workshop.Results:There was a significant difference between the total scores before and after the intervention, with a large effect size. Post-intervention scores were significantly improved in 8 items, namely those related to the reporting of: (i) the content of any suicide note; (ii) headlines with methods of suicide; (iii) headlines with the location of suicide; (iv) cases of suspected suicide despite the unconfirmed cause of death; (v) suicide news to cater to readers’ interests; (vi) cause of suicide; (vii) details of the location of suicide; and (viii) the negative impact to media community when reporting suicide stories. In particular, there was an improvement in the majority of items for people from the media community with no lived experience of suicidal behavior.Conclusion:The media safe reporting workshop is a potentially effective intervention for improving awareness and knowledge measures relating to safe reporting on suicide among the media community, with a more pronounced effect in those without lived experience of suicidal behavior. Limitations in the sample size, generalizability, short-term evaluation, and lack of a control group warrant future larger, longer-term controlled, and more representative studies. (shrink)

Evidence suggests divergent thinking is the cognitive basis of creative thoughts. Neuroimaging literature using resting-state functional connectivity has revealed network reorganizations during divergent thinking. Recent studies have revealed the changes of network organizations when performing creativity tasks, but such brain reconfigurations may be prolonged after task and be modulated by the trait of creativity. To investigate the dynamic reconfiguration, 40 young participants were recruited to perform consecutive Alternative Uses Tasks for divergent thinking and two resting-state scans were used for mapping (...) the brain reorganizations after AUT. We split participants into high- and low-creative groups based on creative achievement questionnaire and targeted on reconfigurations of the two brain networks: default-mode network and the network seeded at the left inferior frontal gyrus because the between-group difference of AUT-induced brain activation located at the left IFG. The changes of post-AUT RSFCs indicated the prolonged effect of divergent thinking. More specifically, the alterations of RSFCIFG−AG and RSFCIFG−IPL in the high-creative group had positive relationship with their AUT performances, but not found in the low-creative group. Furthermore, the RSFC changes of DMN did not present significant relationships with AUT performances. The findings not only confirmed the possibility of brain dynamic reconfiguration following divergent thinking, but also suggested the distinct IFGN reconfiguration between individuals with different creativity levels.

Prediction is one of the major challenges in complex systems. The prediction methods have shown to be effective predictors of the evolution of networks. These methods can help policy makers to solve practical problems successfully and make better strategy for the future.

A recommendation system is then used to identify the products that correspond to the production capacity of each individual country but are somehow overlooked by (...) the country. Then, we simulate the evolution of the country’s fitness if it would have followed the recommendations. The result of this work is the combination of these two methods to provide insights to countries on how to enhance the diversification of their exported products in a scientific way and improve national competitiveness significantly, especially for developing countries.

This study aims to investigate whether simple and convenient progressive relaxation training is effective in enhancing collegiate student athletes’ mental health and sports performance. An experimental group of 14 and a control group of 10 collegiate student athletes were recruited from among track and field athletes who were preparing for provincial competition. The experimental group was exposed to a PRT intervention in 30-min sessions conducted twice per week for a duration of one month. At baseline, the Competitive State Anxiety Inventory-2, (...) State-Trait Anxiety Inventory, and Eysenck Personality Questionnaire-Revised Short Scale for Chinese were completed, while only the CSAI-2 was reassessed at one, two, and three weeks after initiation of the intervention. Additionally, within half a day after completing all one’s individual competition events, the CSAI-2 was again assessed in the two groups recalling their memory of their precompetition state anxiety. Then, the differences in the three dimensions of the CSAI-2 between the two groups at the five time points introduced above were compared. This study also explored whether PRT affected sports performance, defined by the athletes reaching their best records or not, by logistic regressive analysis. This study found significant between-group differences in the self-confidence dimension score at the second and third time points. Through logistic regression analysis, a positive effect of PRT was found for the enhancement of sports performance. In sum, PRT showed positive effects on precompetition state self-confidence and enhanced sports performance among collegiate student athletes. (shrink)
