There is an important contemporary debate in moral responsibility about whether the following asymmetry thesis is true: moral responsibility for actions does not require alternative possibilities but moral responsibility for omissions does. In this paper, we do two things. First, we consider and reject a recent argument against the asymmetry thesis, contending that the argument fails because it rests on a false view about the metaphysics of omissions. Second, we develop and defend a new argument against the asymmetry thesis, one (...) that avoids the problem with the first argument by not resting on any assumptions about what omissions are metaphysically.

The United Nations ‘Transforming our world: the 2030 Agenda for Sustainable Development’ lays out 17 Sustainable Development Goals to address a range of global issues related to the future of the planet and human well-being. Critics, however, argue that the Agenda, a complex product of multi-stakeholder governance, in its drive to accommodate many competing voices, is overloaded with weakly defined, overlapping and contradictory issues, concepts and buzzwords. These serve to gloss over actual concrete global problems and forces, concealing an underlying (...) free-trade ideology. In this paper, using Multimodal Critical Discourse Analysis, we draw attention to the nature of the documents used to communicate the Agenda. These documents comprise an edifice of self-referential texts that rely heavily on infographics, bullet points, charts and tables. Such formats appear to helpfully simplify, distil information and break things down into workable components. But, we show, through the affordances of these formats, the the vagueness of buzzwords, contradictions and lack of clear causalities can be glossed over, presenting the Agenda as a highly technical, engaging, and above all moral process. These formats are important, therefore, for the legitimization and rhetorical power of the Agenda, necessary for its take-up by governments and organizations around the world. (shrink)

ObjectiveSelf-esteem and self-acceptance are not only basic features but also influential factors of mental health. The present study aimed at assessing the effects of psychoeducational lecture and group intervention on self-esteem and self-acceptance in Chinese college students.MethodsA total of 149 Chinese college students who participated in a mental health course were randomly class-based assigned into the psychoeducational lecture group and the self-focused intervention group. The lecture group received 6-session psychoeducational lectures on overview of mental health, campus adaptation, stress adjustment, self-understanding, (...) emotion management, and interpersonal relationships. The self-focused intervention group was treated with self-related group activities involving aspects of self-knowledge, self-feeling, and self-regulation for six sessions. Pre- and post-intervention measurements were taken with Rosenberg Self-Esteem Scale and Self-Acceptance Questionnaire for both groups.ResultsSelf-esteem significantly increased in both groups after six sessions. However, the enhancement of self-acceptance was more robust for the self-focused intervention group than the psychoeducational lecture group.ConclusionThe psychoeducational lecture and self-focused intervention were effective approaches to improve self-esteem for Chinese college students. With respect to self-acceptance, self-focused group intervention might have a more prominent effect. (shrink)

This article proposes a systematic application of recent developments in the logic of preference to a number of topics in deontic logic. The key junction is the well‐known Hansson conditional for dyadic obligations. These conditionals are generalized by pairing them with reasoning about syntactic priority structures. The resulting two‐level approach to obligations is tested first against standard scenarios of contrary‐to‐duty obligations, leading also to a generalization for the Kanger‐Anderson reduction of deontic logic. Next, the priority framework is applied to model (...) two intuitively different sorts of deontic dynamics of obligations, based on information changes and on genuine normative events. In this two‐level setting, we also offer novel takes on vexed issues such as the Chisholm paradox and modelling strong permission. Finally, the priority framework is shown to provide a unifying setting for the study of operations on norms as such, in particular, adding or deleting individual norms, and even merging whole norm systems in different manners.

BackgroundThe neural activity of irritable bowel syndrome patients in the resting state without any intervention has not been systematically studied. The purpose of this study was to compare the resting-state brain functions of IBS patients with healthy controls.MethodsThe published neuroimage studies were obtained from electronic databases including PubMed, EMBASE, PsycINFO, Web of Science Core, CNKI Database, Wanfang Database, VIP Database, and CBMdisc. Search dates were from inception to March 14th, 2022. The studies were identified by the preidentified inclusion and exclusion (...) criteria. Two independent reviewers compiled the studies and evaluated them for quality and bias.ResultsAltogether 22 fMRI studies were included in this review. The risk of bias of the included studies was generally low. The findings indicated that in IBS patients, increased or decreased brain areas were mostly associated with visceral sensations, emotional processing, and pain processing. According to brain network research, IBS may exhibit anomalies in the DMN, CEN, and emotional arousal networks. The fluctuations in emotion and symptoms in IBS patients were associated with alterations in the relevant brain regions.ConclusionThis study draws a preliminary conclusion that there are insufficient data to accurately distinguish the different neurological features of IBS in the resting state. Additional high-quality research undertaken by diverse geographic regions and teams is required to reach reliable results regarding resting-state changed brain regions in IBS. (shrink)

The economic restructuring and rapid rise of the economy in Northeast China have resulted in a proliferation of new ventures. Studying the psychology of new entrepreneurs is conducive to understanding the relationship between human capital and economic growth. The work reported here aims to explore the impact of human capital on economic growth in Northeast China and the influencing factors of psychological capital of new entrepreneurs in the entrepreneurial process. Based on Cobb–Douglas production function, the relationship between labor, physical capital, (...) or human capital and economic growth in Northeast China is analyzed by econometric methods, and a model of human capital and economic growth in Northeast China is constructed. Besides, a psychological capital intervention model is proposed to develop the psychological capital of new entrepreneurs, and the psychological quality structure model of entrepreneurial entrepreneurs and its operation mechanism. The results of the empirical analysis demonstrate that the elasticity coefficient of human capital in Northeast China is 0.15902, five times smaller than that of labor and physical capital. Moreover, 70% of new ventures are willing to accept higher education. The fitting degree of using the PCI model to develop the psychological capital of new ventures is only 0.3%. In addition, the modified external environment PCI instead of the external environment PCI model has a huge operating potential in the macro-entrepreneurial environment. In conclusion, the impact of human capital on economic growth in the northeast is smaller than the impact of labor and material capital investment on regional economic growth. The development of human capital and research on the composition and mechanism of psychological quality of entrepreneurial entrepreneurs are of significant theoretical and practical values to promote the economic growth in the northeast.

The biotech revolution profoundly changes and reconstructs the Foucaultian concept of biopolitics from different dimensions. It declares the coming of the Age of Biocapitalism, which opens a new pattern of modern power allocation of life governance and shows people two prospects simultaneously: utopian hopes and dystopian desperation. Biocapitalism has not only produced ethical degeneration and cultural shock, but more importantly, has opened new areas for political hegemony and economic aggression through the reconstruction of biopolitics, and the enhancement of capital’s comprehensive (...) dominance on nature and the human society. Therefore, it has become an area of serious, scholarly research in the biotech era to explore the implications of contemporary biopolitics, to take precautions against, and reduce the real risks of technocapitalism. This paper investigates the new biopolitics supported by the manipulation of modern biotechnology, especially genetic engineering, and unveils the possible hazards and deep contradictions inherent in this capital-controlled science, within the context of biocapitalism. It also seeks ways to prevent technological alienation and to reconstruct political rationality. It argues that entrepreneurs, scientists, companies and universities of developed countries must realize the limits of capital expansion and the self―regulatory capability of the market, and, then, assume ethical responsibilities as biocapital holders.

Host-microbiome interactions (HMIs) are critical for the modulation of biological processes and are associated with several diseases, and extensive HMI studies have generated large amounts of data. We propose that the logical representation of the knowledge derived from these data and the standardized representation of experimental variables and processes can foster integration of data and reproducibility of experiments and thereby further HMI knowledge discovery. A community-based Ontology of Host-Microbiome Interactions (OHMI) was developed following the OBO Foundry principles. OHMI leverages established (...) ontologies to create logically structured representations of microbiomes, microbial taxonomy, host species, host anatomical entities, and HMIs under different conditions and associated study protocols and types of data analysis and experimental results.

Although multimodal input has the potential to lead to more sound learning outcomes, it carries the risk of causing cognitive overload, making it difficult to determine the exact effects of multimodal input on the second language phrase learning. This study tests the efficacy of multimodal input on L2 phrase learning. It adopts a mixed-method approach by utilizing both quantitative and qualitative data. The experimental design is a 2 × 3 mixed model, with a group [the experimental group and the control (...) group ] as the between-subject factor and time as the within-subject factor. A total of 66 participants were divided into two groups. All materials incorporated three aspects of phrase knowledge, but the materials of the CG were unimodal in that they were offered only on paper, and of the EG were multimodal in that they included pictures, audio recordings, and video clips. After the treatment, a questionnaire and a semi-structured interview were given to the EG learners to explore their perceptions of using multimodal materials to learn L2 phrases. The results indicate that both groups had significant gains in learning phrases, but students with the multimodal input achieved significantly better results than those with the unimodal input. Moreover, the EG students had a generally positive attitude toward the use of multimodal resources. This study validates the efficacy of multimodal input on the acquisition of English phrases and shows that cognitive overload was avoided by sequencing the information. (shrink)

When humans are confronted with an epidemic situation or a continuous natural disaster, success depends largely on how critical information is conveyed to as many people as possible, how individuals' emotional experiences of the crisis are elicited, and how their behaviors are directed going forward. Efficient publicity is key to successful epidemic prevention and control. This study explores the role of creative publicity by comparing the influence of creative publicity and general publicity in different periods of the COVID-19 outbreak in (...) China. The effects of creative and general publicity differed across varying periods of the COVID-19 outbreak. Specifically, compared to general publicity, creative publicity had a significant impact on individuals' emotional arousal in the early period of the COVID-19 outbreak while it significantly promoted individuals' emotional arousal, behavioral regulation, and willingness to actively disseminate information in the middle period. In the stable period of the COVID-19 outbreak, creative publicity performed better than general publicity in regulating individuals' behavior. On the other hand, general publicity was more effective than creative publicity in regulating individuals' behavior and actively disseminating information about the epidemic in the early period of the COVID-19 outbreak. In conclusion, creative and general publicity had differing effects in different periods of the COVID-19 outbreak, which may relate to the characteristics of the publicity format and people's psychological conditions in different periods of the COVID-19 outbreak.

Background: The pregnancy and psychological status of infertile couples has always been a concern, but there is no clear evidence for the efficacy of psychotherapy for infertile couples. This study aimed to summarize the current evidence of the effects of psychotherapy on psychological and pregnancy outcomes for infertile couples. Method: We searched Ovid MEDLINE, Ovid EMbase, The Cochrane Library, and Web of Science for articles published from 1946 to June 26, 2020. The pregnancy outcomes, psychological outcomes, and acceptability were involved (...) in the study. Results: Overall, 29 studies with a combined total of 3,522 adult participants were included in the meta-analysis. Compared with a placebo, psychotherapy was associated with the pregnancy rate [risk ratio = 1.43, 95% CI [1.07, 1.93]], total psychological scales associated with infertility [standardized mean difference = −0.33 95% CI [−0.63, −0.02]], subsymptoms of psychological scores using the 28-item version of GHQ, and the integrative body–mind–spirit ; total psychological scales associated with infertility using other treatments and more than a month; and anxiety using BMS had significant statistical significance. The funnel plots of all outcomes were approximately symmetrical, and no significant publication bias was found. Conclusions: The study showed that psychotherapy can lead to improvements in the pregnancy rate for infertile patients, especially for patients receiving assisted fertility. In addition, it may help improve total psychological scales associated with infertility and depression. CBT and BMS play an important role in improving rate of pregnancy, and BMS is associated with reducing anxiety. Although psychological interventions had limited effects on the pregnancy outcomes of infertility, our study still recommended that psychotherapies, in particular CBT and BMS, were applied to the therapeutic regimen for infertility, especially for patients receiving assisted fertility.

Nelson Goodman (1906-2007) approached the arts and other kinds of knowledge as forms of symbolism. His principal aim in philosophy was to advance understanding and remove confusions by verbal analysis and logical constructions. Goodman's philosophical theories encompass nominalism, constructivism and a version of radical relativism. In his Languages of Art, Goodman sets forth distinctions among the various art according to differences in the forms of symbols employed.

Public value facilitates the democratization of public policy making, it should be the common-sense and bottom-line for policymakers. However, it has not been paid enough attention by the practical and theoretical circles. How to realize the transformation from individual value to public value and make public policies be in line with citizens’ preferences, is vital for the democratic politics. How individual value becomes public value in the agenda-setting stage during the policy-making process? What are the key influencing factors? Using the (...) case of Yangzhou Chemical Co. Youjia Program and interview data, this paper studies the mechanisms that could make individual value be transformed to public value through deeply observing and measuring individuals’ attitudes, demands, motivations, beliefs, and preferences. We argue that (1) public value is an essential foundation for agenda setting and guidance to policy making, whereas individual value cannot naturally substitute value orientation in the public sphere. (2) Transferring individual value to public value can reduce divergence appearing in the subsequent stage in policy activities. (3) Factors that can influence this transformation are policy subjects, relations, rule and expression channels with various determinants and conditions. (4) Public value can terminate irrational and unreasonable policies or drag the policy issues back into the agenda-setting stage. This paper provides unique insights into why individual citizens enter the public sphere to take public actions so that the Chinese government can recognize additional public opinions, which makes cooperative governance be realized.

BackgroundIndividuals with mind-wandering experience their attention decoupling from their main task at hand while others with flow experience fully engage in their task with the optimum experience. There seems to be a negative relationship between mind-wandering and flow. However, it remains unclear to what extent mind-wandering exerts an impact on flow. And it is also elusive whether physical activity and mindfulness, which are as important factors that affected individuals’ attentional control and psychological health, are beneficial in explaining the association between (...) mind-wandering and flow. The current study investigated the relationship between mind-wandering and flow, and the potential mediation effects of physical activity and mindfulness in this association.MethodsA cross-sectional exploratory study design, including multiple scales such as the Mind-Wandering Questionnaire, the International Physical Activity Questionnaire Short Form, Mindfulness Attention and Awareness Scale, and the Short Dispositional Flow Scale was applied. Descriptive statistics and bivariate correlation coefficients were applied in the analysis of these data. A multiple mediation model was used to examine the relationships between mind-wandering, flow, physical activity, and mindfulness.ResultsMind-wandering was inversely associated with physical activity, mindfulness and flow, respectively; and flow was positively related to physical activity and mindfulness, respectively. Moreover, multiple mediation results demonstrated that physical activity and mindfulness, respectively, mediated the relationship between mind-wandering and flow.ConclusionThese findings are helpful to understand how our minds attend to the present moment, and the crucial roles of physical activity and mindfulness in the association between mind-wandering and flow. An implication of these is the possibility that the effective strategies aimed at enhancing both the levels of physical activity and mindfulness are needed to reduce the negative impact of mind-wandering on flow.

Brain structural covariance network can delineate the brain synchronized alterations in a long-range time period. It has been used in the research of cognition or neuropsychiatric disorders. Recently, causal analysis of structural covariance network, winner-take-all and cortex–subcortex covariance network, and modulation analysis of structural covariance network have expended the technology breadth of SCN. However, the lack of user-friendly software limited the further application of SCN for the research. In this work, we developed the graphical user interface toolkit of brain structural (...) covariance connectivity based on MATLAB platform. The software contained the analysis of SCN, CaSCN, MOD-SCN, and WTA-CSSCN. Also, the group comparison and result-showing modules were included in the software. Furthermore, a simple showing of demo dataset was presented in the work.

This work firstly reviewed two existing CL-taVNS forms: motor-activated auricular vagus nerve stimulation and respiratory-gated auricular vagal afferent nerve stimulation, and then proposed three future CL-taVNS systems: electroencephalography -gated CL-taVNS, electrocardiography -gated CL-taVNS, and subcutaneous humoral signals -gated CL-taVNS. We also highlighted the mechanisms, targets, technical issues, and patterns of CL-taVNS. By reviewing, proposing, and highlighting, this work might draw a preliminary blueprint for the development of CL-taVNS.

Transgender women experience serious psychiatric problems and high suicide rates. According to the interpersonal theory of suicide, thwarted belongingness and perceived burdensomeness play major roles in suicidality and can be measured by the Interpersonal Needs Questionnaire. However, no study has validated the use of the INQ in TGW. This study aimed to examine the psychometric properties of the INQ among TGW. We recruited 198 TGW from Shenyang, China, using snowball sampling. The construct validity of the INQ was assessed through factor (...) analysis, and convergent and divergent validity were examined through a structural equation model with other psychosocial factors. The construct validation analysis supported a three-factor model with satisfactory fit indices: χ2/df = 1.54, RMSEA = 0.052, CFI = 0.931, TLI = 0.916, SRMR = 0.053. The thwarted belongingness was significantly associated with self-esteem and social support, and the social exclusion was significantly associated with loneliness, depression, entrapment, and defeat, suggesting satisfactory convergent and divergent validity for the three-factor model. The present findings indicate that for TGW, high social exclusion is important in assessing perceived interpersonal needs, while the notable deviation from previous two-factor model warrants further study.

In recent years, somatosensory interaction technology, represented by Microsoft’s Kinect hardware platform, has been widely used in various fields, such as entertainment, education, and medicine. Kinect technology can easily capture and record behavioral data, which provides new opportunities for behavioral and psychological correlation analysis research. In this paper, an automatic decision-style recognition method is proposed. Experiments involving 240 subjects were conducted to obtain face data and individual decision-making style score. The face data was obtained using the Kinect camera, and the (...) decision-style score were obtained via a questionnaire. To realize automatic recognition of an individual decision-making style, machine learning was employed to establish the mapping relationship between the face data and a scaled evaluation of the decision-making style score. This study adopts a variety of classical machine learning algorithms, including Linear regression, Support vector machine regression, Ridge regression, and Bayesian ridge regression. The experimental results show that the linear regression model returns the best results. The correlation coefficient between the linear regression model evaluation results and the scale evaluation results was 0.6, which represents a medium and higher correlation. The results verify the feasibility of automatic decision-making style recognition method based on facial analysis. (shrink)

Abnormal behaviour detection algorithm needs to conduct behaviour analysis on the basis of continuous video inclination tracking, and the robustness of the algorithm is reduced for the occlusion of moving targets, the occlusion of the environment, and the movement of targets with the same colour. For this reason, the optical flow information between RGB images and video frames is used as the input of the network in view of group behaviour. Then, the direction, velocity, acceleration, and energy of the crowd (...) were weighted and fused into a global optical flow descriptor. At the same time, the crowd trajectory map is extracted from the original image of a single frame. Following, in order to realize the detection of large displacement moving target and solve the problem that the traditional optical flow algorithm is only suitable for the detection of displacement moving target, a video abnormal behaviour detection algorithm based on the double-flow convolutional neural network is proposed. The network uses two network branches to learn spatial dimension information and temporal dimension information, respectively, and uses short- and long-time neural network to model the dependency relationship between long-time video frames, so as to obtain the final behaviour classification results. Simulation test results show that the proposed method can achieve good recognition effect on multiple datasets, and the performance of abnormal behaviour detection can be significantly improved by using interframe motion information.
