We study the computational complexity of finding a line that bisects simultaneously two sets in the two-dimensional plane, called the pancake problem, using the oracle Turing machine model of Ko. We also study the basic problem of bisecting a set at a given direction. Our main results are: (1) The complexity of bisecting a nice (thick) polynomial-time approximable set at a given direction can be characterized by the counting class #P. (2) The complexity of bisecting simultaneously two linearly separable nice (...) (thick) polynomial-time approximable sets can be characterized by the counting class #P. (3) For either of these two problems, without the thickness condition and the linear separability condition (for the two-set case), it is arbitrarily hard to compute the bisector, even if it is unique.

Though more connected today than ever before, the Far East and the West are still divided by an issue which first arose more than 400 years ago: the complaint of the West that its ideology has never been fully adopted by China. To provide a useful conceptual framework for a discussion of this intriguing situation, this essay invokes the instructive give-and-take of market exchange on the famed Silk Road in the long ancient past and takes a careful and close look (...) at the analogous enactment of the same principle in the quiet but consequential transplantation of Chinese horticultural and related philosophical ideas to England and continental Europe in the seventeenth and eighteenth centuries and in the initially skeptical but eventually appreciative reception of many Western political and technological ideas in China in the last two centuries.

This study aimed to investigate the effects of customers’ motivations on online purchase intentions as mediated by commitment toward online fashion retailers. The survey method was used to collect data from Chinese respondents using a questionnaire. The convenience sampling technique was used to collect data from 275 respondents. Collected data were analyzed on smart-PLS using the structural equation modeling technique. Results of the study show a significant and positive impact of social empowerment and remuneration motivations on consumer commitment online purchase (...) intention. Further results show that consumer commitment partially mediates the relationship between social empowerment, remuneration, and online purchase intention. This study contributes to the literature in the domain of consumer commitment by focusing on the underlying needs and motivations of consumers. The researchers have demonstrated a strong need to understand the dynamics of commitment due to its importance in affecting purchase intention. This study also has several implications that guide online retailers how to motivate consumers with social, remuneration and empowerment incentives to develop their intention to purchase online. Fashion retailers are suggested to gratify certain consumer motives to increase commitment. Specifically, among the three motives, empowerment motivation emerged as the strongest predictor of consumer commitment in social media environment. This study will help to the online brands to attract more customers by providing the motivation such financial, empowerment and socialization. (shrink)

This study explores the research paradigms of contemporary business ethics research in 2001–2008. With citation data from the top two business ethics journals included in the Social Sciences Citation Index, this study conducts citation and co-citation analysis to identify the most important publications, scholars, and research themes in the business ethics area and then maps the intellectual structure of business ethics studies between 2001 and 2008. The results show that current business ethics studies cluster around four major research themes, including (...) morality and social contract theory, ethical decision making, corporate social responsibility, and stakeholder theory. This study helps profile the invisible network of knowledge production in business ethics and provides important insights on current research paradigms of business ethics studies. (shrink)

This paper investigates how social trust affects stock price synchronicity using a large sample of listed firms in China. We propose and provide evidence that social trust has a significantly positive impact on the amount of firm-specific information capitalized into stock prices. Further analyses indicate that firms located in regions of high social trust tend to have a smaller stock price crash risk and are less likely to engage in opportunistic behaviors than those in low-trust regions. Moreover, the positive role (...) of trust in increasing firm-specific return variations and discouraging corporate misbehaviors is more pronounced for SOEs than Non-SOEs. Evidence from 2SLS regressions supports a causal impact of social trust on stock price synchronicity. (shrink)

The article is devoted to social problems of modern science (as it were interpreted Max Weber) considered in the context of the system-communicative approach by N. Luhmann. In contrast to the modern work of art, the modern science, as M. Weber believes, is associated with the fundamental unattainability of “true being”, and, as a result, with the transitory character of any scientific achievement. The specialty of modern science, as Weber noted, is determinated, on the one hand by its self-understanding, due (...) to the “peculiarity of the current moment”, and, on the other, by its transformation into a kind of blind spot of scientific observation. As a result, Weber formulated the main problem of the meaning of modern science: he wondered why any scientist needs a science under (1) external alienation and (2) inaccessibility of a scientific object? Moreover, the category of truth not just acquires its special value, but also sets a special meaning to the purpose of scientific communication, that becomes an object but not a property of scientific search. The main content of the article is the study of the Weberian concepts of the external (science as a profession) and internal (science as vocation) social factors of modern science as they were interpreted by E. von Kahler, G. Rickert, M. Scheller, K. Loewit. The authors discuss their attempts to modernize the fundamental Weberian distinction of truth/value as a principle of inclusion in the scientific community, that was formulated as a response to the “Weber’s challenge”. The authors argue that von Kahler criticized the Weberian concept for the incompatibility of the spatial and temporal discreteness of science within the “organic understanding” of the unity of the world. At the same time Scheler and Rickert payed special attention to the problem of subject specification of science. K. Levit discussed the possibility of Weber’s substitution of objectivity as a key distinction of modern knowledge with some opposite attribute. In the final part, the authors summarize the inconsistency of predictions about the further internal differentiation of scientific disciplines and the rejection of research motive for “genuine being”.

With the development of artificial intelligence technologies, it is possible to use computer to read digital medical images. Because Alzheimer’s disease has the characteristics of high incidence and high disability, it has attracted the attention of many scholars, and its diagnosis and treatment have gradually become a hot topic. In this paper, a multimodal diagnosis method for AD based on three-dimensional shufflenet and principal component analysis network is proposed. First, the data on structural magnetic resonance imaging and functional magnetic resonance (...) imaging are preprocessed to remove the influence resulting from the differences in image size and shape of different individuals, head movement, noise, and so on. Then, the original two-dimensional ShuffleNet is developed three-dimensional, which is more suitable for 3D sMRI data to extract the features. In addition, the PCANet network is applied to the brain function connection analysis, and the features on fMRI data are obtained. Next, kernel canonical correlation analysis is used to fuse the features coming from sMRI and fMRI, respectively. Finally, a good classification effect is obtained through the support vector machines method classifier, which proves the feasibility and effectiveness of the proposed method. (shrink)

The article substantiates that science, thanks to the latest media in the dissemination of scientific communication (especially computer word processing, big data accumulation, mega-science installations, the latest international networking platforms and collaborations), has gone beyond all institutional, organizational, regional, national and partly disciplinary borders. Science as a supranational communication system has reached a complexity that is incompatible with the standards for evaluating scientific work and scientific achievements, which are traditionally carried out in the form of scientific committees, individual examinations and (...) other collegial forms of scientific communication. The collegiality of making the most important decisions regarding the examination of the scientific product itself, the thematic agenda, professional competencies and the resulting distribution of remuneration, reputation, ranks, degrees, grants has exhausted its capabilities to a certain extent. As a result, science turns out to be opaque both for the regulator, who is trying to exercise control over scientific institutions, and for science itself, which in the form of scientific self-government and philosophical reflection of science carries out the function of self-observation and self-description. A working hypothesis is proposed, which states that in response to this crisis of collegiality, reflection and control, new media of communicative success and new organizational forms of scientific communication crystallize in science, which can restore the ability of a scientific system to process its internal and external complexity. These media are represented by a new, social-networked form of scientific expertise and partly scientific work, which will be able to compensate for the lack of self-reflection, both at the organizational level of research institutes and at the level of global control over science as a whole.

First of all, I consider it necessary to note that the full value of freedom of existence of religious organizations operating in the territory of our country, the realization of their tasks, goals depends first of all on the effective mechanism of their legal support and legal guarantees. It is clear that the legal norms fixed in the legislation of Ukraine, which relate to the sphere of freedom of religion, concern only the plane of realization of freedom of conscience - (...) freedom of religious expression both at the individual and the collective levels. This is an extremely pressing issue that needs scientific reflection. (shrink)

STS scholarship has produced important insights about relationships between the roles of peer review and the social construction of knowledge. Yet, barriers related to access have been a continual challenge for such work. This article overcomes some past access challenges and explores peer review normativities operating in the new discipline of Engineering Education. In doing so, it contributes new insights about disciplinary development, interdisciplinarity, and peer review as a site of knowledge construction. In particular, it draws attention to an aspect (...) of peer review not previously discussed – how peer review normativities are shaped by disciplinary origins. A content analysis of peer review documentation revealed that a hyperfocus on methods, which can be traced back to disciplinary origins, continues to be a guiding normativity. However, interviews with editors revealed that they do not acknowledge that normativity. Implications of those findings and their misalignment are discussed, as are contrasts with the history of other disciplines. (shrink)

This study tested whether compassionate goals to support others and self-image goals to maintain and defend desired self-images: 1) are equivalent constructs across three cultures ; 2) overlap with interdependent self-construal; and 3) predict relationships and growth measures similarly in each country. We re-analyzed data from American and Japanese students, reported in Niiya et al., along with new data from Poland. Single and multiple group confirmatory analyses showed that the two-factor structure holds across the three cultures. Interdependence correlated with compassionate (...) and self-image goals only in Japan. In all three samples, compassionate goals correlated with non-zero-sum belief, feeling close, growth-seeking, self-compassion, and learning from failures, whereas self-image goals correlated with defensive responses to conflicts and validation-seeking. Our results suggest that compassionate and self-image goals may serve similar functions in relationships and growth across cultures. (shrink)

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.

Recently, the use of new educational technologies in language teaching development is expanding rapidly. Educational technologies attach new features to the learning environments. The integration of educational technologies in language teaching has been received special attention among language researchers. In so doing, the present study investigated language learners’ perceptions of the integration of innovative educational technologies in their language classrooms. The sample comprised 301 English as a foreign language students with different academic qualifications from Shaanxi Province and other provinces in (...) China. To gather the necessary data, the researcher conducted a technology integration questionnaire and a focus group interview. The results of obtained data demonstrated that the language learners had positive attitudes toward using technology in their classrooms. However, the findings of the interviews indicated that learners had some problems such as lack of technology literacy and inadequate assess to facilities in participating in technology-based classroom activities.

Grapheme-colour synaesthetes experience unusual colour percepts when they encounter letters and/or digits. Studies of English-speaking grapheme-colour synaesthetes have shown that synaesthetic colours are sometimes triggered by rule-based linguistic mechanisms . In contrast, little is known about synaesthesia in logographic languages such as Chinese. The current study shows the mechanisms by which synaesthetic speakers of Chinese colour their language. One hypothesis is that Chinese characters might be coloured by their constituent morphological units, known as radicals, and we tested this by eliciting (...) synaesthetic colours for characters while manipulating features of the radicals within them. We found that both the function and position of radicals influence the nature of the synaesthetic colour generated. Our data show that in Chinese, as in English, synaesthetic colours are influenced by systematic rules, rather than by random associations, and that these rules are based on existing psycholinguistic mechanisms of language processing.

At this stage of evolution of our discipline, philosophy of science, there seems no single great theme that has attracted the attention of most practitioners in the field. Rather, scholarly works in the field are quite diffused. Traditional topics, such as reductionism and the unity of science, remain to be carefully examined from various perspectives. The debate over realism versus instrumentalism, although dismissed by some as uninteresting and unproductive, is still taken by many active scholars as vital in our understanding (...) of the nature of scientific theories and in our appraisal of scientific enterprise. Of course, the new spirit of our times has also shown itself, sometimes in the discussion of some major theses in the post-empiricist philosophy of science, such as incommensurability, underdetermination and constructivism, on the basis of detailed examination of scientific materials, other times in the shift of the attention from static aspects of science, such as theory justification and the nature of explanation, to more dynamic aspects, such as negotiations within a scientific community and its function and role in the development of science. Even more to the point in this regard is the great attention paid to the place science has occupied in modernity, the defect of modernist understanding of science and its possible remedy. Not surprisingly, this current state of affairs in our field has also manifested in the essays collected in this volume of contributions to the Twentieth World Congress of Philosophy. Thus, an inspection of these essays, although it will not provide us with a focus of the discipline, may give us some sense as to what is going on in the field. (shrink)

In his work, the author critically interprets the idea of the connection of the achievements of William Whewell in the field of the philosophy of science with the prevailing sentiments and social-cultural attitudes in the so-called Victorian era. The author believes that, on the contrary, all of Whewell’s positive achievements should be associated with the development of world science, with the spirit of the times, and above all, with its neo-Kantian background, whereas his mistakes and delusions (rejection of evolutionism, support (...) for the idea of phlogiston) really resulted from specifically English conservatism and blind trust in the actual social institutions and ideas both in science and in politics.

Problematic issues of freedom of religion in their theoretical and practical comprehension, in particular their contemporary analysis in the context of the principles enshrined in the Vatican II adopted by the document on freedom of religion - the Declaration of "Dignitatis humanae" - "Dignity of the human" are extremely relevant and important as a philosophical- legal and religious studies, and in theological discourses.

The discovery of America was one of the major events that determined the establishment of the world-historical process. However, for a long time this large-scale and all-important phenomenon, as well as the concept itself, was interpreted strictly in accordance with the Eurocentric attitudes and assessments of history. The European outlook tended to review the ambiguous, heterogeneous in its content, and accompanied by contradictions phenomenon in narrow geographical, political, economic, and epistemological perspectives. The usual interpretation lacked the cultural-historical, philosophical, and cultural (...) meanings. The author of the article attempts to fill the lost meanings and to expand the very meaning of the concept of “the discovery of America” by changing perspectives - from the European to the American one, in which the concept reaches a new interpretative level by having defined the continent-wide culture-forming strategy, and is able to absorb many meanings of self-identification of the subject involved in the global historical process.
