Our model integrates the nativist assumption of prespecified neural structures underpinning basic emotions with the constructionist view that emotions are assembled from psychological constituents. From a dynamic systems perspective, the nervous system self-organizes in different ways at different time scales, in relation to functions served by emotions. At the evolutionary scale, brain parts and their connections are specified by selective pressures. At the scale of development, connectivity is revised through synaptic shaping. At the scale of real time, temporary networks of (...) synchronized activity mediate responses to situations. To the degree that humans share common emotional functions, neural structuration is similar across scales, giving rise to “basic” emotions. However, unique developmental and situational factors select for neural configurations mediating emotional variants. (shrink)

The aim of this study is to explore social media marketing activities and their impact on consumer intentions. This study also analyzes the mediating roles of social identification and satisfaction. The participants in this study were experienced users of two social media platforms Facebook and Instagram in Pakistan. A self-administered questionnaire was used to collect data from respondents. We used an online community to invite Facebook and Instagram users to complete the questionnaire in the designated online questionnaire system. Data were (...) collected from 353 respondents, and structural equation modeling was used to analyze the data. Results show that SMMAs have a significant impact on the intentions of users. Furthermore, social identification mediates the relationship between social media activities and satisfaction, and satisfaction mediates the relationship between social media activities and the intentions of users. This will help marketers how to attract customers to develop their intentions. This is the first novel study that used SMMAs to address the user intentions with the role of social identification and satisfaction in the context of Pakistan. (shrink)

The main purpose of this study is to probe into the human capacity of understanding systems and defects in human knowledge of the world. The study addresses the greyness levels and systems levels and explains why the world cannot be perceived as a purely white or black structure. It also clarifies why human knowledge of systems always remains grey. The investigation relies on logical and deductive reasoning and uses the theoretical foundations of systems thinking and Boulding’s systems hierarchy. The most (...) important argument that this study advances is that human knowledge, in any form or under any circumstances, is grey and incomplete and will remain grey. Because the notion of “perfect knowledge” is ambiguous given human epistemic limits, any proportion of knowledge is incomplete and prone to change. Less complexity could lead to more accurate predications, but even in the simplest forms of systems, reaching perfect knowledge seems to be an unwarranted claim. Furthermore, because our perception of past events is incomplete, we cannot predict the future with certainty, as a result of which both the past and the future appear grey to us. The world, as an integrated system, is neither black nor white, but it remains grey, and the systems partially recognized by humans are part of the grey world. Gaining knowledge and increasing discoveries only contribute to the grey systems that are already known. (shrink)

Every scientific or intellectual movement is founded upon basic assumptions and hypotheses that shape its specifically formulated philosophy. This study seeks to explore and explicate the basic philosophical underpinnings of grey systems theory, as well as the paradigm governing its postulates. The study, more specifically, scrutinizes the underlying principles of GST from the perspective of postmodern philosophy. To accomplish this, the epistemology, ontology, human nature, and methodology of GST are substantially investigated in the light of postmodern philosophy. The study draws (...) on Burrell and Morgan’s framework to reveal the paradigm underlying the philosophy of GST. Results demonstrate that GST is an anti-realistic, anti-positivistic, and non-deterministic theory which is inherently pluralistic and ideographic. Based on the principles of GST, change is an indispensable dimension of human speculation about the world and systems, and knowledge is ceaselessly reproduced as new information is collected. As a result, knowledge, narratives, theories and scientific laws are dynamically changed. GST, then, is remarkably compatible with the foundations of postmodern thought and it could be regarded as a postmodern theory governed by a humanistic paradigm. (shrink)

By PFM, we mean a finitely generated module over a principal ideal domain; a linear sentence is a sentence that contains no disjunctive and negative symbols. In this paper, we present an algorithm which decides the truth for linear sentences on a given PFM, and we discuss its time complexity. In particular, when the principal ideal domain is the ring of integers or a univariate polynomial ring over the field of rationals, the algorithm is polynomial-time. Finally, we consider some applications (...) to Abelian groups. (shrink)

The novel coronavirus (COVID-19) has imperatively shaken the behavior of the global financial markets. This study estimated the impact of COVID-19 on the behavior of the financial markets of Europe and the US. The results revealed that the returns of the S&P 500 index have been greatly affected by a lockdown in the US owing to COVID-19. However, the health crisis generated due to the novel coronavirus significantly decreased the stock returns of the Nasdaq Composite index. The results also showed (...) that the economic crisis generated from the pandemic in Spain has had more impact on the IBEX 35 as compared to the health crisis itself. On the other hand, in the long-run, Italy’s stock markets are more affected by the health crisis as contrasted with the economic crisis, while, in the short-run, both lockdown conditions and economic instability lower the stock returns of FTSE MIB. The UK stock markets witnessed that in the short-run, deficiency of health management systems imperatively damaged the stock returns of the London Stock Exchange. The investigation revealed that deficiency of health systems and lockdown conditions have imperatively damaged the structure of financial markets, inferring that sustainable development of these nations is at risk due to COVID-19. The study suggested that governments should allocate more of their budget to the health sector to overcome a health crisis in the future. (shrink)

Coinciding with the rising development of emerging markets, sustainable consumption practices in these markets are increasingly under scrutiny. In this context, we compare empirical results from consumers in four countries (three emerging markets and one developed market) in an experimental study to uncover patterns of preferences for sustainable luxury products (i.e., products that combine sustainability and luxury characteristics). Our findings illustrate that consumers’ quality, emotional, price, and social value perceptions, as well as purchase and electronic word-of-mouth intentions, are consistently higher (...) in all three emerging markets compared to the developed market. We find that sustainability (vs. conventional) product features increase consumers’ product value perceptions and behavioral intentions, although this effect is partially stronger for the developed compared to the emerging market(s). We further show a positive sustainability effect for luxury products, this effect is stronger for mass-market products. Combining sustainability and luxury signals leads to similar effects in emerging and developed markets. Thus, emerging markets have promise in terms of scope for incorporating sustainability characteristics into luxury products. Sustainable luxury consumption can therefore be understood as a manifestation of global consumer culture. (shrink)

The onset of the Covid-19 pandemic has disrupted the lives of families in the United States and across the world, impacting parent mental health and stress, and in turn, the parent-child relationship. Music is a common parent-child activity and has been found to positively impact relationships, but little is known about music’s role in parent-child interactions during a pandemic. The current study utilized an online questionnaire to assess the use of music in the home of young children and their parents (...) in the United States and Canada during Covid-19 and its relationship with parents’ affective attachment with their child. Musical activity was high for both parents and children. Parents reported using music for both emotion regulation and to socially connect with their children. Parent-child musical engagement was associated with parent-child attachment, controlling for relevant parent variables including parent distress, efficacy, education, and parent-child engagement in non-musical activities. These results indicate that music may be an effective tool for building and maintaining parent-child relationships during a period of uncertainty and change. (shrink)

This study seeks to explicate the philosophical foundations and theoretical outlines of grey systems theory by focusing on human perception, cognition, and understanding processes and by considering their functions in the process of producing knowledge. Primarily, the study investigates the processes of perception, cognition, and understanding, as well as their dynamicity. Then, it is explained how knowledge is produced through the interpretation/understanding of information and data and through the dynamicity governing this process. The findings reveal that human perception, cognition, and (...) understanding perpetually remain grey and imperfect, while lost sensatory data mark the very first aspect of greyness in such human capabilities. Furthermore, any piece of data, as a discrete and single entity, represents a determinate fact, symbol or signal from the world, while any set of data, no matter how large, remains incomplete and imperfect, and human beings always interpret inadequate sets of data in the world. Therefore, information and knowledge always remain grey and uncertain because they deeply rely on subjective understandings/interpretations and work with imperfect inputs and sets of data. The impact of knowledge on action and interaction and their effects on the world are some factors adding to the dynamicity of the world. Constant change in world data, outdated knowledge, defects in datasets, and human biases in understanding all confirm the infinitely grey nature of human knowledge of the world. (shrink)

Advances in artificial intelligence have raised a basic question about human intelligence: Is human reasoning best emulated by applying task‐specific knowledge acquired from a wealth of prior experience, or is it based on the domain‐general manipulation and comparison of mental representations? We address this question for the case of visual analogical reasoning. Using realistic images of familiar three‐dimensional objects (cars and their parts), we systematically manipulated viewpoints, part relations, and entity properties in visual analogy problems. We compared human performance to (...) that of two recent deep learning models (Siamese Network and Relation Network) that were directly trained to solve these problems and to apply their task‐specific knowledge to analogical reasoning. We also developed a new model using part‐based comparison (PCM) by applying a domain‐general mapping procedure to learned representations of cars and their component parts. Across four‐term analogies (Experiment 1) and open‐ended analogies (Experiment 2), the domain‐general PCM model, but not the task‐specific deep learning models, generated performance similar in key aspects to that of human reasoners. These findings provide evidence that human‐like analogical reasoning is unlikely to be achieved by applying deep learning with big data to a specific type of analogy problem. Rather, humans do (and machines might) achieve analogical reasoning by learning representations that encode structural information useful for multiple tasks, coupled with efficient computation of relational similarity.

In studies investigating the property value enhancements along metro lines, study ranges in most cases are measured in Euclidean distance. However, city roads are not always straight, and Euclidean distance sometimes does not equal to actual distance the passenger travels from the public transport station to their home or a commercial spot. To solve this problem, this study analyzed the indicators affecting commercial property value in metro station accessible area in Xi’an, using walking time consumption in measuring the study range. (...) Following a conceptual framework, considering empirical evidences in related studies, information in city structure, and metro distribution, the initial indicator set is built. Using hedonic price model, spatial autoregressive model, and error term, significant indicators affecting commercial property value are investigated. In this study, 14 significant indicators are determined and quantified. Threshold distance equals to 900 m is found to be appropriate in addressing the autocorrelation problem with the weighted decision matrix tool. Compared to HPM and SEM, SAR is found to perform the best in evaluating the significant indicators with the largest R2 and the lowest Akaike Info Criterion. Besides, it is discovered that the value of the commercial property lies in the study range of 20 min walking time and is obviously influenced by the metro station. The results discovered in this study could provide some empirical evidences to commercial property planning in Xi’an. (shrink)

It has been a growing trend in Chinese universities to shift from English for general purposes to English for specific purposes teaching. Against this background, large groups of teachers previously engaged in teaching EGP have become or are becoming ESP teachers, which means a complex process of learning for subject-specific information, transforming teaching practices and constructing new identities. Despite this, very little has been written about the ESP teacher cognition of language teaching or the factors influencing this shift in teaching. (...) This study involved English for Medical Purposes teachers in Chinese universities as participants, and a scale of EMP TC with 31 items was developed on the basis of questionnaire results. Data from exploratory factor analysis revealed six dimensions of the scale, namely, teacher attitude, teacher belief, teacher learning, teacher support, role identification, and teacher practice—that combine to constitute and influence EMP TC. While the identity factor has attracted wide attention in ESP teacher research, other factors have largely been neglected. Thus, this research highlights the importance of more factors in shaping and changing the language teaching cognition of EMP or ESP teachers in large, especially the teacher belief factor. In addition, results of independent samples t-tests indicated significant difference in EMP teacher learning in terms of gender, differences in EMP teacher attitude and teacher support in terms of EMP teaching experience. Suggestions for enhancing EMP TC are offered on the basis of the conclusions of this research. (shrink)

Overall, the research found a positive and significant application of modern dance and creation from dialectical materialist philosophy. Modern dance and creation have a direct influence on dialectical materialist philosophy. (shrink)

In this paper, I discuss, in a Heideggerian context, the possibility of de-subjectivizing the notion of the transcendental time-horizon and reinterpreting it as a formally indicated ‘whereto’ of releasement. The structures of the time-horizon depict the way beings unfold in the fullness of time in their alterity, and they orient the subject’s activity of ‘projection.’ What results is a field-oriented (as opposed to self-oriented) transcendental philosophy which would survive Heidegger’s critique of his own transcendental project, and which would avoid mystification. (...) I take three steps. First, I point out that the problematization of ‘transcendental Heidegger’ is based on the subjectivist interpretation of the time-horizon. I problematize a recent account in the subjectivist vein, arguing that it is neither indispensable, nor very plausible, nor the most illuminative of Heidegger’s work. Second, with the help of Dahlstrom, Golob, Engelland, Sheehan, and Vasterling, I gradually dissociate the notion of the horizon from subjectivism, the visual metaphor, and the assumption of an absolute ground. I suggest instead that the horizonality of the horizon be understood temporally, i.e., as an interplay of presencing and absencing where what matter most are the structures, themselves affected by time, which the transcendental field displays when beings unfold themselves within it. Third, I identify three of those structures when performing a de-subjectivizing reading of Heidegger’s interpretation of the threefold synthesis in Kant’s A-Deduction. These structures capture the way every being manifests itself, without themselves being necessarily grounded in the subject’s activity. This gives an example of how transcendental philosophy can clarify what the time-horizon is like while bracketing the question of its provenance. (shrink)

Every scientific or intellectual movement rests on central premises and assumptions that shape its philosophy. The purpose of this study is to review a brief account of the main philosophical bases of grey systems theory (GST) and the paradigm governing its principles. So, the recent studies on the philosophical foundations of GST have been reviewed and tried to pay attention to some key ambiguities in the previous studies and give more and clearer explanations in this paper. Also, this paper tries (...) to fill the gap among the previous studies and to provide a purposeful connection between them by expressing two key concepts: complete information and imbalance knowledge. Primarily, the study addresses the theoretical foundations of uncertainty and the concept of greyness. Next, it focuses on the notion of “complete information” and challenges to it. Then, it reviews such processes as perception, cognition, and understanding, as well as their dynamic nature. It explains how knowledge is produced through understanding and interpreting information/data and the dynamics governing the whole process. Also, the study describes any dataset, no matter how large it may be, will remain incomplete, imperfect, and grey, so humans only rely on incomplete datasets to interpret the world. As such, information and knowledge are always grey and uncertain because they are basically contingent on subjective understandings and interpretations and imperfect inputs and data. Finally, as a key development, this study also demonstrates that human grey knowledge remains imbalanced across different disciplines and spheres. In the end, a brief overview of the philosophical paradigm of GST is also provided. GST is depicted as an anti-realistic, anti-positivistic, and non-deterministic approach, which is inherently pluralistic and ideographic. According to GST principles, dynamicity and change are essential parts of human narratives of the world and systems, and human knowledge is constantly reproduced through collecting new information. As a result, knowledge, theories, narratives, and scientific laws dynamically change. Given this premise, one could argue that GST is considerably compatible with the postulates of post-modern thinking. (shrink)

Although Chinese Marxism—primarily represented by Maoism—is generally seen by Western intellectuals as monolithic, Liu Kang argues that its practices and projects are as diverse as those in Western Marxism, particularly in the area of aesthetics. In this comparative study of European and Chinese Marxist traditions, Liu reveals the extent to which Chinese Marxists incorporate ideas about aesthetics and culture in their theories and practices. In doing so, he constructs a wholly new understanding of Chinese Marxism. Far from being secondary considerations (...) in Chinese Marxism, aesthetics and culture are in fact principal concerns. In this respect, such Marxists are similar to their Western counterparts, although Europeans have had little understanding of the Chinese experience. Liu traces the genealogy of aesthetic discourse in both modern China and the West since the era of classical German thought, showing where conceptual modifications and divergences have occurred in the two traditions. He examines the work of Mao Zedong, Lu Xun, Li Zehou, Qu Qiubai, and others in China, and from the West he discusses Kant, Schiller, Schopenhauer, and Marxist theorists including Horkheimer, Adorno, Benjamin, and Marcuse. While stressing the diversity of Marxist positions within China as well as in the West, Liu explains how ideas of culture and aesthetics have offered a constructive vision for a postrevolutionary society and have affected a wide field of issues involving the problems of modernity. Forcefully argued and theoretically sophisticated, this book will appeal to students and scholars of contemporary Marxism, cultural studies, aesthetics, and modern Chinese culture, politics, and ideology.

Background While the number of emergency patients worldwide continues to increase, emergency doctors often face moral distress. It hampers the overall efficiency of the emergency department, even leading to a reduction in human resources. Aim This study explored the experience of moral distress among emergency department doctors and analyzed the causes of its occurrence and the strategies for addressing it. Method Purposive and snowball sampling strategies were used in this study. Data were collected through in-depth, semi-structured interviews with 10 doctors (...) working in the emergency department of a tertiary general hospital in southwest China. The interview data underwent processing using the Nvivo 14 software. The data analysis was guided by Colaizzi’s phenomenological analysis method. Study findings This study yielded five themes: (1) imbalance between Limited Medical Resources and High-Quality Treatment Needs; (2) Ineffective Communication with Patients; (3) Rescuing Patients With no prospect of treatment; (4) Challenges in Sustaining Optimal Treatment Measures; and (5) Strategies for Addressing Moral Distress. Conclusion The moral distress faced by emergency doctors stems from various aspects. Clinical management and policymakers can alleviate this distress by enhancing the dissemination of emergency medical knowledge to the general public, improving the social and economic support systems, and strengthening multidisciplinary collaboration and doctors’ communication skills.

The present work aims to efficiently carry out life-death education for college students, improve their psychological problems, and reduce suicide accidents by combining LDE with Dance Movement Therapy. DMT is a psychosomatic cross therapy that treats mental or physical diseases through dance or improvisation. Firstly, this paper introduces LDE and DMT and designs the activities of DMT intervention. Secondly, the relationship between DMT and LDE is analyzed. Finally, a questionnaire survey is conducted on the research objects. The research objects are (...) divided into the experimental group receiving DMT intervention, the control group participating in sports dance courses, and the benchmark group. The research data show no significant difference in interpersonal skills and emotional psychology among the three groups. The DMT intervention group has substantial changes in other factors except for the conflict control ability before and after the intervention. In addition, the questionnaire survey results after the intervention demonstrate that the DMT intervention group gets a significantly higher score in the interpersonal relationship, interpersonal relationship building ability, moderate rejection ability, self-disclosure ability, and emotional support ability. Therefore, DMT intervention positively impacts college students’ interpersonal relationships. After the sports dance course, there are differences in the total score of interpersonal ties and scores of interpersonal relationships building ability, self-disclosure ability, and emotional support ability in the control group, but with no significant difference in moderate rejection ability and conflict control ability. Therefore, compared with traditional psychotherapy methods, the DMT method reported here is conducive to releasing pressure and alleviating physical and mental anxiety. The research content provides new ideas for psychological education in colleges and universities and contributes to improving college students’ suicidal tendencies and helping college students grow up healthily.

In this paper, a robust H ∞ control problem of a class of linear parabolic distributed parameter systems with pointwise/piecewise control and pointwise/piecewise measurement has been investigated via the robust H ∞ feedback compensator design approach. A unified Lyapunov direct approach is proposed in consideration of the pointwise/piecewise control and point/piecewise measurement based on the distributions of the actuators and sensors. A new type of Luenberger observer is developed on the continuous interval of space domain to track the state of (...) the system, and an H ∞ performance constraint with prescribed H ∞ attenuation levels is proposed in this paper. By utilizing Lyapunov technique, mathematical inequalities, and integration theory, a sufficient condition based on LMI for the exponential stability of the corresponding closed-loop coupled system under an H ∞ performance constraint is presented. Finally, the effectiveness of the proposed design method is verified by numerical simulation results. (shrink)

Firms tend to seek optimal distinctiveness when choosing CSR engagement timing. Building on the perspectives of optimal distinctiveness and competitive dynamics, this paper explains why firms' CSR engagement timing toward a certain event is affected by dynamic competitive effects. That is, to achieve optimal distinctiveness, focal firms pay more attention to their main competitors that are similar in market, size and resources. We apply a discrete-time survival analysis of 869 Chinese listed firms' CSR engagement action toward the COVID-19 pandemic during (...) the first half of 2020. The results support the mechanism that when a highly similar competitor engages in CSR activities, it raises the probability that the focal firm engages itself beyond levels based solely on its own characteristics and common time-dependent factors.
