As the prevalence of self-harm among adolescents in Chinese escalates, finding out the potential risk factors associated with self-harm behaviors has aroused much attention. This study aims to explore the association between parent-child separation and series of self-harm subtypes among Chinese adolescents. We survey a total of 4,928 middle school students aged from 12 to 18 years at school. Parent-child separation was investigated from four dimensions—occurrence of parental separation, separation status, age at first separation and duration of separation. Self-harm series (...) are deemed as five subtypes—highly lethal self-harm, less lethal self-harm with visible tissue damage, self-harm without visible tissue damage, self-harmful behaviors with latent damage and psychological self-harm. Multivariate logistic regression is used to explore the associations between parent-child separation and different subtypes of self-harm among adolescents. Paternal separation is associated with each type of self-harm whilst maternal separation is not correlated with highly lethal self-harm. Except for highly lethal self-harm, the other four subtypes of self-harm demonstrate a relation with both length of paternal separation and maternal separation with aOR ranging from 1.02 to 1.06. Individuals who suffer parental separation prior to the age of three were at a higher risk for four types of less-lethal self-harm. The association of parent-child separation with self-harm deserves our attention, and future research is needed to identify the underlying mechanisms. (shrink)

According to pragmatic encroachment, whether an epistemic attitude towards p has some positive epistemic status (e.g., whether a belief is epistemically rational or justified, or it amounts to knowledge) partially depends on practical factors such as the costs of being wrong or the practical goals of the agent. Pragmatic encroachment comes in many varieties. This survey article provides an overview of different kinds of pragmatic encroachment. It focuses on three dimensions under which kinds of pragmatic encroachment differ: the type of (...) epistemic status affected by practical factors, the type of practical factors affecting the epistemic status, and the type of normative considerations encroaching on the epistemic status.

According to doxastic pragmatism, certain perceived practical factors, such as high stakes and urgency, have systematic effects on normal subjects’ outright beliefs. Upholders of doxastic pragmatism have so far endorsed a particular version of this view, which we may call threshold pragmatism. This view holds that the sensitivity of belief to the relevant practical factors is due to a corresponding sensitivity of the threshold on the degree of credence necessary for outright belief. According to an alternative but yet unrecognised version (...) of doxastic pragmatism, practical factors affect credence rather than the threshold on credence. Let’s call this alternative view credal pragmatism. In this paper, I argue that credal pragmatism is more plausible than threshold pragmatism. I show that the former view better accommodates a cluster of intuitive and empirical data. I conclude by considering the issue of whether our doxastic attitudes’ sensitivity to practical factors can be considered rational, and if yes, in what sense. (shrink)

According to evidentialist views, credence in a proposition p should be proportional to the degree of evidential support that one has in favor of p. However, empirical evidence suggests that our credences are systematically sensitive to practical factors. In this article, I provide a cost–benefit analysis of credences' practical sensitivity. The upshot of this analysis is that credences sensitive to practical factors fare better than practically insensitive ones along several dimensions. All things considered, our credences should be sensitive to practical (...) factors. (shrink)

Background: The prevalence of sedentary behavior in adolescents has aroused social attention. The association between sedentary behavior and cognitive flexibility remains unclear, and it may vary depending on the type of sedentary behavior. This study aimed to investigate the associations between specific-type sedentary behaviors and cognitive flexibility in adolescents.Method: A total of 700 Chinese adolescents aged 10–15 years were recruited. The self-report questionnaire was used to assess total sedentary time, recreational screen-based sedentary time, and educational sedentary time. The More-odd shifting (...) task was used to assess cognitive flexibility.Results: The correlation analysis showed that recreational screen-based sedentary time was negatively correlated with cognitive flexibility, whereas educational sedentary time was positively correlated with cognitive flexibility. The regression analysis also further revealed that a significantly negative association between recreational screen-based sedentary time and cognitive flexibility, while a significantly positive association existed between educational sedentary time and cognitive flexibility.Conclusion: The findings shown that the association between recreational screen-based sedentary behavior and cognitive flexibility differs from educational sedentary behavior in adolescents, providing new ideas for a more comprehensive understanding of the association between sedentary behavior and cognitive flexibility in adolescents.

ObjectiveThis study took users of short-form mobile videos as research participants to explore the role of their boredom proneness in mediating the relationship between the use of mobile social media and subjective well-being.MethodsA sample of 656 users was evaluated by the Problematic Mobile Social Media Usage Assessment Questionnaire, General Well-Being Schedule, and Boredom Proneness Scale.ResultsFirstly, significant interactions were found between monthly living expenses and the UMSM of the participants, which were recognized as factors affecting SWB. Secondly, the level of living (...) expenses had little effect on the high-level and low-level groups of the UMSM but imposed a significant impact on the medium-level group. Thirdly, the UMSM showed an influence that could positively predict boredom; both the UMSM and boredom demonstrated a negative predictive effect on SWB.ConclusionThe findings indicate that the inappropriate use of mobile social media negatively affects users’ subjective well-being; boredom partially mediated the relationship between the use of mobile social media and SWB.

In this note we shall describe the lattice of the congruences on a balanced Ockham algebra with the pseudocomplementation whose quotient algebras are boolean. This is an extension of the result obtained by Rodrigues and Silva who gave a description of the lattice of congruences on an Ockham algebra whose quotient algebras are boolean.

During immune responses against invading pathogenic bacteria, the cytoskeleton network enables macrophages to implement multiple essential functions. To protect the host from infection, macrophages initially polarize to adopt different phenotypes in response to distinct signals from the microenvironment. The extracellular stimulus regulates the rearrangement of the cytoskeleton, thereby altering the morphology and migratory properties of macrophages. Subsequently, macrophages degrade the extracellular matrix (ECM) and migrate toward the sites of infection to directly contact invading pathogens, during which the involvement of cytoskeleton‐based (...) structures such as podosomes and lamellipodia is indispensable. Ultimately, macrophages execute the function of phagocytosis to engulf and eliminate the invading pathogens. Phagocytosis is a complex process that requires the cooperation of cytoskeleton‐enriched super‐structures, such as filopodia, lamellipodia, and phagocytic cup. This review presents an overview of cytoskeletal regulations in macrophage polarization, ECM degradation, migration, and phagocytosis, highlighting the pivotal role of the cytoskeleton in host defense against infection.

Resumo: Após o reinado do Imperador Jiajing, da Dinastia Ming, à medida que o problema dos piratas japoneses se tornava cada vez mais grave, começaram a ser publicados livros dedicados ao estudo do Japão. Entre eles, os mais importantes são Uma Breve Pesquisa do Japão (Ri Ben Kao Lue), Uma Compilação de Mapas Japoneses (Ri Ben Tu Zuan), O Espelho do Japão (Ri Ben Yi Jian), Uma pesquisa do Japão (Ri Ben Kao), Um registro de Costumes Japoneses (Ri Ben Fen (...) Tu) Ji) e A Biografia de Piratas Japoneses em Qiantai (Qian Tai Wo Zhuan). Entre eles, O Espelho do Japão é um especial. Além disso, há também livros especiais para apresentar a situação geral do Japão, como A Coleção de Mapas Militares Costeiros (Chou Hai Tu Bian), Resistência aos Piratas Japoneses na Dinastia Ming (Huang Ming Yu Wo Lu), a Compilação de Defesa Costeira (Hai Fang Zuan Yao) e a Continuação da Categoria de Defesa Costeira nas Regiões Zhedong e Zhexi ( Liang Zhe Hai Fang Lei Kao Xu Bian). Como Zheng Shungong, autor do livro O Espelho do Japão, visitou o Japão duas vezes, muitos conteúdos do livro são baseados em sua própria experiência e conhecimento. Portanto, sua pesquisa sobre o Japão foi além da literatura semelhante da Dinastia Ming, em amplitude, profundidade e precisão. Além disso, o registro e as análises dos piratas japoneses no livro são de grande valor de pesquisa. Antes da publicação dos Anais do Japão (Ri Ben Tu Zhi), de Huang Zunxian, O Espelho do Japão era uma das monografias de mais alto nível sobre o Japão, na China antiga. (shrink)

ObjectivesThe study aims to investigate the state anxiety of parents of special needs children during the 2019 coronavirus disease epidemic and the influence of parental stress, social support, and other related variables on the anxiety of parents.MethodsBespoke questionnaires of children’s and parent’s mental and behavioral problems during the epidemic were used in the study. We also used the State Anxiety Inventory, the Parenting Stress Index—Short Form-15, the NEO Five-Factor Inventory, and the Multidimensional Scale of Perceived Social Support. The data used (...) in the study were pooled from an online survey of parents of special needs children and analyzed by one-way analysis of variance and multiple linear regression.ResultsOverall, 1,451 individuals were included, of which 402 were fathers and 1,049 were mothers. ANOVA results showed that educational background, family monthly income, and type of their child’s disability made parents’ state anxiety significantly different. The results of multiple linear regression showed that during the epidemic, social support negatively predicted parents’ state anxiety, whereas parenting stress and parental mental and behavioral problems positively predicted parents’ state anxiety.ConclusionsDuring the outbreak of COVID-19, parents of special needs children suffered mental and behavioral problems, together with parenting stress and social support, which influenced their state anxiety. These findings can be used to develop relevant psychological interventions to improve the mental health of vulnerable groups during a pandemic like COVID-19. (shrink)

It has been argued recently that knowledge is the norm of practical reasoning. This norm can be formulated as a bi-conditional: it is appropriate to treat p as a reason for acting if and only if you know that p. Other proposals replace knowledge with warranted or justified belief. This paper gives counter-examples of both directions of any such bi-conditional. To the left-to-right direction: scientists can appropriately treat as reasons for action propositions of a theory they believe to be false (...) but good approximations to the truth for present purposes. Cases based on a variant of Pascal’s Wager and actions performed by a skeptic also illustrate the point. To the right-to-left direction: in certain circumstances, it can be unreasonable for a scientist to reason from propositions of a theory she knows to be true. (shrink)

One challenge for moderate invariantists is to explain why we tend to deny knowledge to subjects in high stakes when the target propositions seem to be inappropriate premises for practical reasoning. According to an account suggested by Williamson, our intuitive judgments are erroneous due to an alleged failure to acknowledge the distinction between first-order and higher-order knowledge: the high-stakes subject lacks the latter but possesses the former. In this paper, I provide three objections to Williamson’s account: i) his account delivers (...) counterintuitive verdicts about what it is appropriate for a high-stakes subject to do; ii) the high-stakes subject doesn’t need iterated knowledge in order to be regarded as appropriately relying on the relevant proposition in practical reasoning; iii) Williamson’s account doesn’t provide a good explanation of why the high-stakes subject would be blameworthy if she were relying on the relevant proposition in her practical reasoning.

Self-deception is typically considered epistemically irrational, for it involves holding certain doxastic attitudes against strong counter-evidence. Pragmatic encroachment about epistemic rationality says that whether it is epistemically rational to believe, withhold belief or disbelieve something can depend on perceived practical factors of one’s situation. In this paper I argue that some cases of self-deception satisfy what pragmatic encroachment considers sufficient conditions for epistemic rationality. As a result, we face the following dilemma: either we revise the received view about self-deception or (...) we deny pragmatic encroachment on epistemic rationality. I suggest that the dilemma can be solved if we pay close attention to the distinction between ideal and bounded rationality. I argue that the problematic cases fail to meet standards of ideal rationality but exemplify bounded rationality. The solution preserves pragmatic encroachment on bounded rationality, but denies it on ideal rationality. (shrink)

The problem of adaptive finite-time fault-tolerant control and output constraints for a class of uncertain nonlinear half-vehicle active suspension systems are investigated in this work. Markovian variables are used to denote in terms of different random actuators failures. In adaptive backstepping design procedure, barrier Lyapunov functions are adopted to constrain vertical motion and pitch motion to suppress the vibrations. Unknown functions and coefficients are approximated by the neural network. Assisted by the stochastic practical finite-time theory and FTC theory, the proposed (...) controller can ensure systems achieve stability in a finite time. Meanwhile, displacement and pitch angle in systems would not violate their maximum values, which imply both ride comfort and safety have been enhanced. In addition, all the signals in the closed-loop systems can be guaranteed to be semiglobal finite-time stable in probability. The simulation results illustrate the validity of the established scheme.

Prior research has demonstrated that the adverse consequences of the coronavirus disease 2019 pandemic may go beyond its economic hardships and physical health concerns, having a significant influence on psychological distress for individuals under quarantine. Nevertheless, relatively little attention has been paid to exploring the risk and protective factors in the link between COVID-19 infection risk and psychological distress among young adults. Following a socioecological framework, the current study examines the moderating role of grit and social support in the association (...) between COVID-19 infection risk and depressive symptoms. A sample of 1,251 young adults under home quarantine was involved in this study, and they were asked to complete a set of self-reported questionnaires online. Results of a linear regression analysis exhibited that COVID-19 infection risk was positively associated with depressive symptoms in young adults in quarantine. Moreover, moderation analyses showed that this association was moderated by perseverance and social support. To be specific, for those reporting higher levels of social support, this linkage was not significantly positive; in contrast, for those reporting lower levels of social support, perseverance was a significant protective factor for depressive symptoms when young adults were exposed to a high infection risk of COVID-19. The current study suggests that greater social support is essential to helping young adults deal with possible negative emotions in the context of the COVID-19 pandemic. Moreover, university-based counseling services should pay specific attention to those young adults with relatively insufficient social support resources and low levels of perseverance. (shrink)

Service recovery performance is very important for the takaful insurance industry for maintaining and attracting new clients, which in turn serves as a competitive advantage for the survival and continued future of the businesses. If the insurance sector could not maintain SRP, then the competitive advantage of the organizations could be decayed. Therefore, under the theoretical foundation of equity theory and resource-based theory, this research has investigated the link between human resources management practices and SRP directly and indirectly through the (...) employee commitment. By using a convenient sampling technique data was collected from the employees working in the Takaful industry in Pakistan to empirically test the proposed hypotheses and validate the findings. Using cross research design and quantitative research approach. The Structural Equation Modeling had presented the positive relationship between HRM practices and SRP. On the other hand, employee commitment had also mediated this relationship. As employee commitment is significantly mediated among most of the HRMP, this aspect is therefore considered to be a big contribution of the study in the context of Pakistan. Based on these findings, the current study has several important implications the practitioners and readers. (shrink)

According to an increasingly popular view in epistemology and philosophy of mind, beliefs are sensitive to contextual factors such as practical factors and salient error possibilities. A prominent version of this view, called credal sensitivism, holds that the context-sensitivity of belief is due to the context-sensitivity of degrees of belief or credence. Credal sensitivism comes in two variants: while credence-one sensitivism (COS) holds that maximal confidence (credence one) is necessary for belief, threshold credal sensitivism (TCS) holds that belief consists in (...) having credence above some threshold, where this threshold doesn’t require maximal confidence. In this paper, I argue that COS has difficulties in accounting for three important features about belief: i) the compatibility between believing p and assigning non-zero credence to certain error possibilities that one takes to entail not-p, ii) the fact that outright beliefs can occur in different strengths, and iii) beliefs held by unconscious subjects. I also argue that TCS can easily avoid these problems. Finally, I consider an alleged advantage of COS over TCS in terms of explaining beliefs about lotteries. I argue that lottery cases are rather more problematic for COS than TCS. In conclusion, TCS is the most plausible version of credal sensitivitism. (shrink)

In this entry, we provide an overview of some of the methodological debates surrounding contextualism and consider whether they are, in effect, based on an underlying methodological dispute. We consider three modes of motivation of epistemic contextualism including i) the method of cases, ii) the appeal to linguistic analogies and iii) the appeal to conceptual analogies and functional roles. We also consider the methodological debates about contextualism arising from experimental philosophy. We conclude that i) there is no distinctive methodological doctrine (...) or set of methodological doctrines that is centrally invoked by all epistemic contextualists and ii) the substantive dispute about the truth of contextualism very frequently, although not invariably, reflects an underlying methodological dispute.

A proposition is noncontingent, if it is necessarily true or it is necessarily false. In an epistemic context, ‘a proposition is noncontingent’ means that you know whether the proposition is true. In this paper, we study contingency logic with the noncontingency operator? but without the necessity operator 2. This logic is not a normal modal logic, because?→ is not valid. Contingency logic cannot define many usual frame properties, and its expressive power is weaker than that of basic modal logic over (...) classes of models without reflexivity. These features make axiomatizing contingency logics nontrivial, especially for the axiomatization over symmetric frames. In this paper, we axiomatize contingency logics over various frame classes using a novel method other than the methods provided in the literature, based on the ‘almost-definability’ schema AD proposed in our previous work. We also present extensions of contingency logic with dynamic operators. Finally, we compare our work to the related work in the fields of contingency logic and ignorance logic, where the two research communities have similar results but are apparently unaware of each other’s work. One goal of our paper is to bridge this gap. (shrink)

Building on the human resource management behavioral and organizational climate literature, this study explores the linkage between socially responsible HRM and employee support for perceived external corporate social responsibility and the underlying social and psychological process. Multilevel analysis of data gathered over two separate periods confirmed that the relationship between SRHRM and employee support for external CSR initiatives of the employing organization is mediated by the organizational CSR climate. Moreover, the indirect effect is contingent on perceived internal CSR. This study (...) extends CSR research into the HRM domain and develops a better understanding of the micro-foundations of CSR by integrating the micro- and macro-perspectives of CSR. Based on the study findings, this paper also discusses theoretical contributions and future research directions. (shrink)

Based on ideology-infused psychological contract theory and cognitive evaluation theory, this study investigated the curvilinear relationship between ethical leadership and employee creativity. A curvilinear mediation model was proposed to explain the impact of ethical leadership on creativity, using employee intrinsic motivation as the mediator. Applying a two wave sampling design that consist 258 employees and their leaders, we found that employee creativity improved as ethical leadership increased from low to moderate levels. However, the employee creativity improvement was attenuated when ethical (...) leadership increased from moderate to high levels. Furthermore, the study also revealed that employee intrinsic motivation partially mediated this curvilinear relationship. The theoretical and managerial implications are discussed. (shrink)

The purpose of this study was to examine the effect of group art therapy using traditional Chinese materials on improving the self-efficacy and social function of individuals diagnosed with schizophrenia. In China, little research has been conducted on patients to measure the effectiveness of group art therapy, especially using traditional Chinese materials. To address this research gap, 104 individuals diagnosed with schizophrenia were tested in a group art therapy program that included 30 treatment sessions and used a wide variety of (...) materials, including traditional Chinese materials, such as Chinese calligraphy, traditional Chinese painting, Chinese embroidery, and Chinese beads. The effect of art therapy was analyzed using the General Self-Efficacy Scale and Scale of Social Skills for Psychiatric Inpatients. This study demonstrates that group art therapy using traditional Chinese materials can improve self-efficacy and social function, reducing social and life function problems, and promote the recovery of individuals diagnosed with schizophrenia.

Contingency and accident are two important notions in philosophy and philosophical logic. Their meanings are so close that they are mixed up sometimes, in both daily life and academic research. This indicates that it is necessary to study them in a unified framework. However, there has been no logical research on them together. In this paper, we propose a language of a bimodal logic with these two concepts, investigate its model-theoretical properties such as expressivity and frame definability. We axiomatize this (...) logic over various classes of frames, whose completeness proofs are shown with the help of a crucial schema. The interactions between contingency and accident can sharpen our understanding of both notions. Then we extend the logic to a dynamic case: public announcements. By finding the required reduction axioms, we obtain a complete axiomatization, which gives us a good application to Moore sentences. (shrink)

The completeness of the axiomatization of contingency logic over symmetric frames has been thought of as a nontrivial job, the unimodal case of which cannot be generalized to the finitely multimodal case, which in turn cannot be generalized to the infinitely multimodal case. This paper deals with the completeness of symmetric contingency logic with unlimitedly many modalities, no matter whether the set of modalities is finite or infinite.

Operators can be compared in at least two respects: expressive strength and deductive strength. Inspired by Hintikka’s treatment of question embedding verbs, the variations of noncontingency operator, and also the various combinations of modal operators and Boolean connectives, we propose a logic with strong noncontingency operator as the only primitive modality. The novel operator is deductively but not expressively stronger than both noncontingency operator and essence operator, and expressively but not deductively weaker than the necessity operator. The frame-definability power of (...) this new logic is in between standard modal logic and noncontingency logic. A notion of bisimulation is proposed to characterize this logic within standard modal logic and first-order logic. Axiomatizations over various frame classes are presented, among which the minimal logic is related to the treatment of an alternative semantics of the agreement operator proposed by Lloyd Humberstone.

This article mainly outlines and explores the art exhibitions held between China and the Soviet Union during the founding of the People's Republic of China. The author examines in detail such aspects of the topic as mutual exchanges of art exhibitions between China and the Soviet Union since the founding of the People's Republic of China. Particular attention is paid to the political background against which the evolution in Chinese art took place, as well as the legacy of Soviet realist (...) art in China in the political context and the interaction of art with politics and state-building. The author emphasizes the positive influence of art exhibitions held by the Soviet Union in China on Chinese art education and the creativity of artists. The main conclusions of this study are that the various exhibitions of Soviet art held in China provided an effective opportunity for Chinese artists to study Soviet realist oil paintings. The emergence of Soviet realism in China also served as an important reference point for the development of Chinese oil painting in the 1950s. The novelty of the study lies in the fact that the author not only analyzed the process of the acceptance and dissemination of Soviet realist art in China, but also examined the beginning and end of artistic exchange between China and the Soviet Union in conjunction with the country's social environment and the political leadership of its leaders.

In this paper, we introduce a notion of ‘disjunctive ignorance’, which is a weak combination of two forms of ignorance in the literature. We propose a logical language with ‘disjunctive ignorance’ as a sole modality, explore the logical properties of this notion and its related notions, and axiomatize it over various frame classes. By finding suitable reduction axioms, we extend the results to the case of public announcements and apply it to Moore-like sentences.

Inspired by an interesting quotation from the literature, we propose four modalities, called ‘sane belief’, ‘insane belief’, ‘reliable belief’ and ‘unreliable belief’, and introduce logics with each operator as the modal primitive. We show that the four modalities constitute a square of opposition, which indicates some interesting relationships among them. We compare the relative expressivity of these logics and other related logics, including a logic of false beliefs from the literature. The four main logics are all less expressive than the (...) standard modal logic over various model classes, and the logics of sane and insane beliefs are, respectively, equally expressive as the logics of unreliable and reliable beliefs on any class of models. The logics of reliable and unreliable beliefs are then combined into a bimodal logic, which turns out to be equally expressive as the standard modal logic. Despite this, we cannot obtain a complete axiomatization of the minimal bimodal logic, by simply translating the axioms and rules of the minimal modal logic $\textbf{K}$ into the bimodal language. We then introduce a schematic modality which unifies reliable and unreliable beliefs and axiomatize it over the class of all frames and also the class of serial frames. This line of research is finally extended to unify sane and insane beliefs and some axiomatizations are given. (shrink)
