Many viruses evolved mechanisms for capping the 5′‐ends of their plus‐strand RNAs as a means of hijacking the eukaryotic messenger RNA (mRNA) splicing/translation machinery. Although capping is critical for replication, the RNAs of these viruses have other essential functions including their requirement to be packaged as either genomes or pre‐genomes into progeny viruses. Recent studies indicate that human immunodeficiency virus type‐1 (HIV‐1) RNAs are segregated between splicing/translation and packaging functions by a mechanism that involves structural sequestration of the 5′‐cap. Here, (...) we examined studies reported for other viruses and retrotransposons that require both selective packaging of their RNAs and 5′‐RNA capping for host‐mediated translation. Our findings suggest that viruses and retrotransposons have evolved multiple mechanisms to control 5′‐cap accessibility, consistent with the hypothesis that removal or sequestration of the 5′ cap enables packageable RNAs to avoid capture by the cellular RNA processing and translation machinery.

ObjectivesTo simulate hemodynamic changes after extraluminal compression in pulsatile tinnitus patients with a prominent transverse-sigmoid sinus junction.MethodsOne patient-specific case was reconstructed based on computed tomography venography images of a PT patient. The compression degree served as a new index in this study. Cases with 10, 20, 30, 40, 50, 60, 70, 80, and 90% of the compression degree of the control subject were constructed. Steady-state computational fluid dynamics were assessed. The wall pressure distribution, wall maximum pressure and flow pattern of (...) the PTSJ were calculated to evaluate hemodynamic differences among all cases.ResultsWith increasing compression, the wall pressure at the compression point and downstream of the PTSJ decreased but increased upstream. When the compression degree exceeded 70%, the upstream pressure increased significantly. Above 50% compression, the blood flow pattern downstream of the sigmoid sinus tended to spiral, especially after 80% compression. Beyond 60% compression, the blood flow pattern under the compression axis became more medial.ConclusionMechanical compression of PTSJ changes wall pressure and blood flow patterns. The degree of compression should be carefully observed to avoid possible complications or reoccurrence. (shrink)

Despite increasing interest being given to dysfunctional customer behavior in multiple service sectors, it is unclear how and why different types of dysfunctional customer behavior affect frontline employees’ emotional labor during the service interactions. Drawing upon the conservation of resources theory, we propose a conceptual model in which verbal abuse, disproportionate demand, and illegitimate complaint differentially influence frontline employees’ emotional labor strategies. Further, the boundary conditions of these relationships are considered by introducing perceived organizational support and customer orientation as moderators. (...) Using survey data from 436 frontline employees of five call centers in China, hypotheses were tested through a hierarchical regression analysis. The results indicated that verbal abuse and illegitimate complaint exerted positive effects on surface acting. Particularly, these positive effects were weaker when frontline employees perceived organizational support was high. Also, verbal abuse’s positive effect on surface acting was weaker when frontline employees’ customer orientation was high. Customer’s verbal abuse, disproportionate demand, and illegitimate complaint negatively influenced frontline employees’ deep acting. The negative effect of disproportionate demand on deep acting was weaker when perceived organizational support was high. However, when frontline employees’ customer orientation was high, the negative effects of disproportionate demand and illegitimate complaints on deep acting were weaker. (shrink)

The understanding of food cue associated neural activations that predict future weight variability may guide the design of effective prevention programs and treatments for overeating and obesity. The current study investigated the association between brain response to different food odors with varied energy density and individual changes of body mass index (BMI) over two years. Twenty-five participants received high-fat (chocolate and peanut), low-fat (bread and peach) food odors and a nonfood odor (rose) while the brain activation was measured using functional (...) magnetic resonance imaging (fMRI). BMIs were calculated with participant’s self-reported body weight and height collected at the time of fMRI scan and again at two years later. Regression analyses revealed significant negative correlations between BMI increase over 2 years and brain activation of the bilateral precuneus and the right posterior cingulate cortex in response to high-fat versus low-fat food odors. In addition, brain activation of the right supplementary motor area in response to food vs non-food odor was negatively correlated to subsequent BMI increase over 2 years. Taken together, the current findings suggest that individual differences in neural responsivity to (high calorie) food odors in brain regions of the default mode and motor control network serve as a neural marker for future BMI change.

This paper proposes a minimal logic of fine-grained information dynamics via belief bases. The framework is shown to be able to accommodate explicit belief, implicit belief, awareness of and awareness that, where awareness of agents is not treated as a tacit premise. A sound and complete axiomatization of static logic is established, upon which a series of dynamic operations are defined. It is argued that these dynamics adapt different scenarios. Our logic is minimal because to each agent we only attach (...) two databases, from which a variety of epistemic attitudes are generated. (shrink)

Relevant research shows teachers’ “psychological power” plays a more essential role in promoting their professional development compared with the powers provided by various external factors, and it is therefore held that exploring college English teachers’ individual psychological power is of great significance. To this end, this study investigated college English teachers’ psychological empowerment via the development and validation of CETPE’s scale. Based on our literature review on psychological empowerment and analysis of teachers professional development’s status quo, we made a working (...) definition of CETPE as a system involving perception of their occupation, sense of competence, experiencing of autonomy, judgment of their impact and understanding of their status. In our study, firstly the literature review and the interview with 17 college English teachers were adopted to conceptualize the dimensions of CETPE, and an exploratory factor analysis of data was conducted from 227 college English teachers and then the subsequent confirmatory factor analysis of data collected from another sample of 1030 generated 15 items belonging to five factors. The findings reveal that CETPE is systematically composed of teachers’ positive perception and experience of work meaningfulness, teaching autonomy, occupational competence, professional impact and social status. This study provides a new path for teachers’ professional development via strengthening their intrinsic driving force and thus helps improve the college English teaching effects. (shrink)

Compared with traditional technological innovation modes, green technology innovation is more targeted for low carbon development and critical support for countries worldwide to combat climate change. The impact of green technology innovation on carbon emissions is considered in terms of fixed effect and mediating effect models through industrial structure upgrading. For this purpose, the sample dataset of 30 provincial administrative areas in China from 2008 to 2020 is employed. The results demonstrate that green technology innovation exerts significantly inhibitory effects on (...) carbon emissions, whose conclusion still holds after removing municipalities and replacing the dependent variable. Industrial structure upgrading is vital for green technology innovation to diminish carbon emissions. There is significant regional heterogeneity in the effects of green technology innovation on carbon emissions, i.e., the direct and indirect impact of green technology innovation on carbon emission reduction is significant in the eastern-central area, but its effect is insignificant in the western region. Therefore, it is essential to realize carbon emission reduction by further bolstering green technology innovation and accelerating industrial structure upgrading to fulfill the synergy of technology and structure.

In this paper, we mainly investigate the existence of states based on the Glivenko theorem in bounded semihoops, which are building blocks for the algebraic semantics for relevant fuzzy logics. First, we extend algebraic formulations of the Glivenko theorem to bounded semihoops and give some characterizations of Glivenko semihoops and regular semihoops. The category of regular semihoops is a reflective subcategory of the category of Glivenko semihoops. Moreover, by means of the negative translation term, we characterize the Glivenko variety. Then (...) we show that the regular semihoop of regular elements of a free algebra in the variety of Glivenko semihoops is free in the corresponding variety of regular semihoops. Similar results are derived for the semihoop of dense elements of free Glivenko semihoops. Finally, we give a purely algebraic method to check the existence of states on Glivenko semihoops. In particular, we prove that a bounded semihoop has Bosbach states if and only if it has a divisible filter, and a bounded semihoop has Riečan states if and only if it has a semi-divisible filter.

This book explores how one can bring about changes in the brain through meditation, both through attention-focus training and through compassion training. Recent findings in the natural sciences have confirmed that it is possible for humans to achieve these structural and functional changes through various life-style practices. It is argued that meditation enables us to influence some aspects of our biological make-up and, for example, could boost our cognitive flexibility as well as our ability to act compassionate. Such changes are (...) likely to facilitate the instilling of a number of epistemic virtues which have great bearing on our quality of life. This book offers the reader an accessible introduction to a set of neuro-enhancement methods, with a special focus on meditation techniques, and explores how such practices could contribute to make us better decision-makers and improve our moral virtues. The book is suitable for anyone looking for a text discussing the effects of neuro-enhancement from a secular ethics perspective. (shrink)

In The Rise of Modern Chinese Thought (2023), Wang Hui unfolds two interrelated threads to help us understand China’s historical transition from the pre-modern to modernity. The first thread reveals institutional change in the socio-political realm, tracing the transition from a society based on enfeoffment (fengjian zhi) in the pre-Qin period, to an empire characterized by centralized administration (junxian zhi) during the Tang–Song eras, and eventually to the modern society that began to emerge in the late Qing period. The second (...) thread concerns the paradigm shift in the intellectual realm, with particular emphasis on moral (including social and political) philosophy—or "worldview" in Wang’s terms. This shift moves from the worldview of the rites and music (liyue), to the worldview of heavenly principle (tianli), and finally to the worldview of universal principle (gongli). This essay reframes Wang’s rich depiction of China’s intellectual history through the evolving relationship between the concepts of "principle" (li) and "things" (wu). Based on Wang’s work, it identifies three fundamental stances of Chinese moral philosophy and suggests the possibility of a fourth kind. (shrink)

It has been argued that affordances are not meaningful and are thus not useful to be applied in contexts where specifically meaningfulness of experience is at stake (e.g. clinical contexts or discussions of autonomous agency). This paper aims to reconceptualize affordances such as to make them relevant and applicable in such contexts. It starts by investigating the ‘ambiguity’ of (possibilities for) action. In both philosophy of action and affordance research, this ambiguity is typically resolved by adhering to the agents intentions (...) and concerns. I discuss some recent accounts of affordances that highlight these concerns but argue that they tend to adopt an ‘atomistic’ approach where there is no acknowledgement of how these concerns are embedded in the agents wider concerns, values, projects and commitments. An holistic approach that does acknowledge this can be found in psychological research on agents having a sense of what they’re doing. I will discuss this research in the second part of the paper and argue that agents can analogously have a sense of what is afforded. This is deemed the entry point for understanding the meaningfulness of affordances. In the final part of the paper I apply this analysis to recent attempts which seek to make sense of authentic and autonomous agency in terms of affordances. (shrink)

In this paper, I will discuss what I will call “skeptical pragmatic invariantism” as a potential response to the intuitions we have about scenarios such as the so-called bank cases. SPI, very roughly, is a form of epistemic invariantism that says the following: The subject in the bank cases doesn’t know that the bank will be open. The knowledge ascription in the low standards case seems appropriate nevertheless because it has a true implicature. The goal of this paper is to (...) show that SPI is mistaken. In particular, I will show that SPI is incompatible with reasonable assumptions about how we are aware of the presence of implicatures. Such objections are not new, but extant formulations are wanting for reasons I will point out below. One may worry that refuting SPI is not a worthwhile project given that this view is an implausible minority position anyway. To respond, I will argue that, contrary to common opinion, other familiar objections to SPI fail and, thus, that SPI is a promising position to begin with. (shrink)

Orthodoxy in the contemporary debate on knowledge ascriptions holds that the truth‐value of knowledge ascriptions is purely a matter of truth‐relevant factors. One familiar challenge to orthodoxy comes from intuitive practical factor effects . But practical factor effects turn out to be hard to confirm in experimental studies, and where they have been confirmed, they may seem easy to explain away. We suggest a novel experimental paradigm to show that practical factor effects exist. It trades on the idea that people (...) retract knowledge attributions when practical factors shift. We also explain why the resulting data raise a serious challenge to orthodoxy. (shrink)

This study adds to the theory of family business management by exploring the effects of family ownership on the corporate misconduct of small firms in the United States. The empirical findings indicate that small family-owned firms are less likely to commit misconduct than small non-family-owned firms. We interpret this finding as family firms aiming to achieve the trans-generational succession of moral capital. Further investigation shows a nonlinear family-ownership–misconduct relationship. A negative relationship between them only appears in mature firms. We further (...) show that for relatively mature firms, only family firms with older owners are less likely to commit corporate misconduct. (shrink)

The article proposes a theoretical model to account for changes in self due to Deep Brain Stimulation. First, we argue that most existing models postulate a very narrow conception of self, and thus fail to capture the full range of potentially relevant DBS-induced changes. Second, building on previous work by Shaun Gallagher, we propose a modified ‘pattern-theory of self’, which provides a richer picture of the possible consequences of DBS treatment.

Affordances are possibilities for action offered by the environment. Recent research on affordances holds that there are differences in how people experience such possibilities for action. However, these differences have not been properly investigated. In this paper I start by briefly scrutinizing the existing literature on this issue, and then argue for two claims. First, that whether an affordance solicits action or not depends on its relevance to the agent’s concerns. Second, that the experiential character of how an affordance solicits (...) action depends on the character of the concern to which it is relevant. Concerns are conceived of as bodily forms of responsiveness, and solicitations are experienced through this responsiveness. The main aim of this paper is to make clear that an understanding of experiential differences in solicitations has to be based on a phenomenological appreciation of how one experiences one’s responsiveness to those solicitations. In the remainder of the paper I show how such a phenomenological appreciation reveals several characteristics of our responsiveness and I briefly explore three of them: valence, force and mineness. In the final section I discuss the self-referentiality of affordances in light of the current proposal, and argue that this self-referentiality is broader than is typically acknowledged. (shrink)

Episodic memories can no longer be seen as the re-activation of stored experiences but are the product of an intense construction process based on a memory trace. Episodic recall is a result of a process of scenario construction. If one accepts this generative framework of episodic memory, there is still a be big gap in understanding the role of the narrative self in shaping scenario construction. Some philosophers are in principle sceptic by claiming that a narrative self cannot be more (...) than a causally inefficacious attributed entity anyway. Thus, we first characterize a narrative self in detail and second we clarify its influential causal role in shaping our episodic memories by influencing the process of scenario construction. This happens at three stages, namely at the level of the input, the output and the process of scenario construction. (shrink)

Epistemic invariantism, or invariantism for short, is the position that the proposition expressed by knowledge sentences does not vary with the epistemic standard of the context in which these sentences can be used. At least one of the major challenges for invariantism is to explain our intuitions about scenarios such as the so-called bank cases. These cases elicit intuitions to the effect that the truth-value of knowledge sentences varies with the epistemic standard of the context in which these sentences can (...) be used. In this paper, I will defend invariantism against this challenge by advocating the following, somewhat deflationary account of the bank case intuitions: Readers of the bank cases assign different truth-values to the knowledge claims in the bank cases because they interpret these scenarios such that the epistemic position of the subject in question differs between the high and the low standards case. To substantiate this account, I will argue, first, that the bank cases are underspecified even with respect to features that should uncontroversially be relevant for the epistemic position of the subject in question. Second, I will argue that readers of the bank cases will fill in these features differently in the low and the high standards case. In particular, I will argue that there is a variety of reasons to think that the fact that an error-possibility is mentioned in the high standards case will lead readers to assume that this error-possibility is supposed to be likely in the high standards case.

This paper presents a novel understanding of the notion of calculability. In Gricean frameworks, calculability is defined in terms of how speakers can infer an implicature. The relevant inferences must e.g. be based on maxims of conversation or cooperation principles. Meanwhile, I suggest to define calculability in terms of when, or under which conditions, speakers can infer an implicature. An implicature is calculable if hearers can infer its existence even supposing that the implicature is not semantically encoded. This approach avoids (...) familiar challenges, including recently prominent challenges from pragmatic particularism. (shrink)

With the idea of analyzing awareness as potential for knowledge, we propose a novel semantics for awareness logic. Expressivities of languages with different combinations of modalities for this semantics are investigated. We explore the properties of our semantics and compare our model with Fagin & Halpern model and the model by Heifetz et al. in partitional settings. A series of equivalence results are established from the comparison. Finally, we provide two axiomatizations for implicit knowledge and explicit knowledge, respectively, and prove (...) soundness and completeness for them. (shrink)

Can affordances help in understanding psychiatric illness and psychopathological experience? In recent work on the philosophy of psychiatry and phenomenology, the answer appears to be a clear ‘yes’, but some recent worries have emerged that the affordance-concept might be “insufficiently discerning” and thus ill-suited to make sense of psychiatric illness and experience. In this paper I briefly review recent attempts to use the affordance-concept to make sense of psychopathology, as well as the worries voiced by the critics. I argue that (...) much of this criticism is, in fact, best understood as a call for more research and offer some exploratory considerations on how this research might proceed. Specifically, I argue that an improved understanding of the self-referentiality that is inherent to experiencing affordances can be useful for psychiatry. (shrink)

EDITOR’S ABSTRACTThe popular Chinese portrayal of the victory of Confucianism, or in Chinese terms “dismiss the hundred schools of thought and revere only the Confucian arts,” has been challenged by some scholars in the past decades. Ding’s essay illustrates not only how it has been challenged but also how the catch phrase influences the scholarly discussion. As he indicates, recent Chinese studies that attempt to subvert the traditional theory share the same “flow.” They fail to note that the expression (...) “dismiss the hundred schools of thought and revere only the Confucian arts” has had very negative connotations since it was invoked by Yi Baisha 易白沙 to harshly denounce Confucianism for being responsible for the centuries-long Chinese autocracy.

The term “know” is one of the ten most common verbs in English, and yet a central aspect of its usage remains mysterious. Our willingness to ascribe knowledge depends not just on epistemic factors such as the quality of our evidence. It also depends on seemingly non-epistemic factors. For instance, we become less inclined to ascribe knowledge when it’s important to be right, or once our attention is drawn to possible sources of error. Accounts of this phenomenon proliferate, but no (...) consensus has been achieved, decades of research notwithstanding. Alexander Dinges offers a fresh examination of this ongoing debate. After reviewing and complementing relevant data from both armchair and experimental philosophy, he assesses extant accounts of this data including semantic, metaphysical, pragmatic, doxastic as well as more recent psychological accounts. Against this background, he offers a novel psychological account based on the idea that non-epistemic factors affect estimates of probability. (shrink)

Anticipation is a crucial perceptual-cognitive skill in fast-ball sports, and the effect of high anxiety on performance has attracted more attention from sports psychologists. Related studies mainly focus on the effect of anxiety on influencing processing efficiency and attentional control during information processing in sport. Attentional Control Theory has been supported by several studies. However, these studies have been criticized by the low ecological validity of task design, such as neglecting the dynamic process of anticipation, and inadequate performance analysis, such (...) as analyzing response accuracy and time separately. Using temporal occlusion paradigm, we tested ACT in a dynamic anticipation process. Eighteen skilled and eighteen less-skilled table tennis players were required to anticipate the serves of opponents under dynamic task constraints and anxiety conditions. High cognitive state anxiety decreased processing efficiency for both groups whereas performance effectiveness did not differ. In addition, it negatively affected processing efficiency in early anticipation compared with late anticipation tasks, suggesting that high cognitive state anxiety may have a greater impact on top-down attentional control. Our findings provide support for ACT and show that anxiety impairs anticipation efficiency and performance, possibly due to an ineffectively attentional shift from external kinematic cues to internal long-term working memory. Findings also have implications for the adaptation of attentional strategies and anxiolytic training. (shrink)

Communication can be risky. Like other kinds of actions, it comes with potential costs. For instance, an utterance can be embarrassing, offensive, or downright illegal. In the face of such risks, speakers tend to act strategically and seek ‘plausible deniability’. In this paper, we propose an account of the notion of deniability at issue. On our account, deniability is an epistemic phenomenon. A speaker has deniability if she can make it epistemically irrational for her audience to reason in certain ways. (...) To avoid predictable confusion, we distinguish deniability from a practical correlate we call ‘untouchability’. Roughly, a speaker has untouchability if she can make it practically irrational for her audience to act in certain ways. These accounts shed light on the nature of strategic speech and suggest countermeasures against strategic speech. (shrink)

Moderate pragmatic invariantism (MPI) is a proposal to explain why our intuitions about the truth-value of knowledge claims vary with stakes and salient error-possibilities. The basic idea is that this variation is due to a variation not in the propositions expressed (as epistemic contextualists would have it) but in the propositions conversationally implicated. I will argue that MPI is mistaken: I will distinguish two kinds of implicature, namely, additive and substitutional implicatures. I will then argue, first, that the proponent of (...) MPI cannot appeal to additive implicatures because they don’t affect truth-value intuitions in the required way. Second, I will argue that the proponent of MPI cannot appeal to substitutional implicatures either because, even though they may have the required effects on truth-value intuitions, they don’t feature in the relevant cases. It follows that MPI is mistaken because whether the proponent of MPI appeals to additive or substitutional implicatures, at least one of the claims that make up her view is false. Along the way, I will suggest principles about implicatures that should be relevant not only to MPI, but to pragmatic accounts of seemingly semantic intuitions in general. (shrink)

The recent literature abounds with accounts of the semantics and pragmatics of so-called predicates of personal taste, i.e. predicates whose application is, in some sense or other, a subjective matter. Relativism and contextualism are the major types of theories. One crucial difference between these theories concerns how we should assess previous taste claims. Relativism predicts that we should assess them in the light of the taste standard governing the context of assessment. Contextualism predicts that we should assess them in the (...) light of the taste standard governing the context of use. We show in a range of experiments that neither prediction is correct. People have no clear preferences either way and which taste standard they choose in evaluating a previous taste claim crucially depends on whether they start out with a favorable attitude towards the object in question and then come to have an unfavorable attitude or vice versa. We suggest an account of the data in terms of what we call hybrid relativism. (shrink)

Relativism entails that sentences like ‘Liquorice is tasty’ are used to assert relativistic propositions—that is, propositions whose truth-value is relative to a taste standard. I will defend this view against two objections. According to the first objection, relativism is incompatible with a Stalnakerian account of assertion. I will show that this objection fails because Stalnakerian assertions are proposals rather than attempts to update the common ground. According to the second objection, relativism problematically predicts that we can correctly assess beliefs as (...) false but faultless. I will show that it doesn't. Such assessments come out as incorrect because correct relativistic assertion requires the absence of a presupposition of non-commonality. (shrink)

While many authors distinguish belief from acceptance, it seems almost universally agreed that no similar distinction can be drawn between degrees of belief, or credences, and degrees of acceptance. I challenge this assumption in this paper. Acceptance comes in degrees and acknowledging this helps to resolve problems in at least two philosophical domains. Degrees of acceptance play vital roles when we simplify our reasoning, and they ground the common ground of a conversation if we assume context probabilism, i.e., that the (...) common ground must be represented with probability spaces rather than possible worlds.

Many experiential properties are naturally understood as dispositions such that e.g. a cake tastes good to you iff you are disposed to get gustatory pleasure when you eat it. Such dispositional analyses, however, face a challenge. It has been widely observed that one cannot properly assert “The cake tastes good to me” unless one has tried it. This acquaintance requirement is puzzling on the dispositional account because it should be possible to be disposed to like the cake even if this (...) disposition has never been manifested. We argue that familiar response strategies on behalf of the dispositionalist fail. These include appeals to conversational implicatures, expressivism, semantic presuppositions and norms of assertion. Against this background, we propose a new analysis in terms of what we call tendencies, where a tendency is a disposition that has been manifested. The acquaintance requirement comes out as an entailment. We point out a hitherto unnoticed parallel to sentences ascribing character traits such as “Hannah is brave,” and extend our tendency-based analysis to this domain. (shrink)
