Comprehensively improving the level of vocational education and teaching quality has become an important initiative to meet the new round of technological revolution and industrial change. The traditional teaching mode can no longer meet the needs of industries and enterprises for job competences, and all higher education institutions are actively thinking about how to carry out teaching reform. Virtual reality can effectively solve the above-mentioned drawbacks, but the hardware facilities of the existing VR systems are extremely expensive, making it impossible (...) to popularize it in teaching. In this context, this paper is based on VR for the design of an interactive teaching platform. This paper discusses the key technologies of virtual reality, introduces the relevant theoretical foundation, and describes the current virtual reality devices with high popularity and their advantages and disadvantages for systematic analysis. From the perspective of teaching design, the design of human-computer interaction teaching process using VR technology to develop learning scenes is studied, introducing 3D modeling techniques, model construction, the production of picture and text panels, the production of video materials, and the establishment of virtual tour guide 3D scenes. The principle of this paper is to build a 3D vision for building 3D views of educational needs to design high quality images and video animation using 3DMAX and unity 3D engines. Then, we introduce the use of VR glasses, smart phones, and Bluetooth wireless handle to build a simple interactive teaching platform; the platform is of low cost of construction and student coverage, to solve the teaching resources shortage, equipment conditions lagging behind, the curriculum content aging, teachers and students who cannot interact in real time, and a series of problems.

Authoritarian leadership is of great significance to eastern countries, including China. Meanwhile, unethical employee behavior also exists in all types of social organizations. The relationship between authoritarian leadership and unethical employee behavior is worth studying. Senior leaders often do not have a direct influence on employees except for through their immediate supervisors. The leadership style of senior leaders also influences the leadership style of their subordinates. This paper studies how authoritarian manager leadership trickles down to unethical employee behavior through authoritarian (...) supervisor leadership and discusses the moderating effect of leader member exchange and an ethical climate. Through a questionnaire survey of 406 pairs of leaders, supervisors, and employees, the research results of the multilevel model show that authoritarian supervisor leadership is positively related to unethical employee behavior, authoritarian supervisor leadership mediates the relationship between authoritarian manager leadership and unethical employee behavior, LMX positively moderates the relationship between authoritarian manager leadership and authoritarian supervisor leadership and moderates the mediating effect of authoritarian supervisor leadership, and, that an ethical climate negatively moderates the relationship between authoritarian supervisor leadership and unethical employee behavior and moderates the mediating effect of authoritarian supervisor leadership.

This essay is an attempt to sketch out two contrasting notions of freedom in the Zhuangzi and the Xunzi . I argue that to understand the classical Chinese formulations of freedom we should look at the concept of hua 化 (transformation or to transform). It is a kind of freedom that highlights the moral and/or spiritual transformation of the self and its entailments on the connection between the self and various domains of relationality. The Zhuangzian hua is the transformation of (...) the self in such a way that the self becomes supremely attuned to the complexity of the world and can thus navigate various domains of relationality with extraordinary grace, ease, and efficacy. The Xunzian hua is the transformation of the self so that the self can extend its relationality to include the entire world and transform it from a raw and uncouth world to a civilized one through ritual practices.

Say that an incomplete d.r.e. degree has almost universal cupping property, if it cups all the r.e. degrees not below it to 0′. In this paper, we construct such a degree d, with all the r.e. degrees not cupping d to 0′ bounded by some r.e. degree strictly below d. The construction itself is an interesting 0″′ argument and this new structural property can be used to study final segments of various degree structures in the Ershov hierarchy.

This paper discusses some paradoxical propositions in Chinese tradition, especially the School of Names. It not only explains what Chinese philosophers mean by these propositions and why there are such paradoxes in Chinese philosophy, but also makes an attempt to formulate these paradoxical propositions in the language of symbolic logic. Meanwhile, the paper makes a comparison between Chinese views about contradiction and Aristotle?s law ot non?contradiction and explores the relation between them. It comes to the conclusion that once the difference (...) between Chinese concept of contraries and Aristotle?s is made clear, inconsistency between Chinese paradoxial propositions and Aristotle?s. law of non-contradiction disappears.

ABSTRACT This study investigated what information about brain death was available from Google searches for five major religions. A substantial body of supporting research examining online behaviors shows that information seekers use Google as their preferred search engine and usually limit their search to entries on the first page. For each of the five religions in this study, Google listings reveal ethical controversy about organ donation in the context of brain death. These results suggest that family members who go online (...) to find information about organ donation in the context of brain death would find information about ethical controversy in the first page of Google listings. Organ procurement agencies claim that all major world religions approve of organ donation and do not address the ethical controversy about organ donation in the context of brain death that is readily available online.

The recent rapid development of information technology, such as sensing technology, communications technology, and database, allows us to use simulation experiments for analyzing serious accidents caused by hazardous chemicals. Due to the toxicity and diffusion of hazardous chemicals, these accidents often lead to not only severe consequences and economic losses, but also traffic jams at the same time. Emergency evacuation after hazardous chemical accidents is an effective means to reduce the loss of life and property and to smoothly resume the (...) transport network as soon as possible. This paper considers the dynamic changes of the hazardous chemicals’ concentration after their leakage and simulates the diffusion process. Based on the characteristics of emergency evacuation of hazardous chemical accidents, we build a mixed-integer programming model and design a heuristic algorithm using network optimization and diffusion simulation. We then verify the validity and feasibility of the algorithm using Jinan, China, as a computational example. In the end, we compare the results from different scenarios to explore the key factors affecting the effectiveness of the evacuation process. (shrink)

As an imitation of the biological nervous systems, neural networks, which have been characterized as powerful learning tools, are employed in a wide range of applications, such as control of complex nonlinear systems, optimization, system identification, and patterns recognition. This article aims to bring a brief review of the state-of-the-art NNs for the complex nonlinear systems by summarizing recent progress of NNs in both theory and practical applications. Specifically, this survey also reviews a number of NN based robot control algorithms, (...) including NN based manipulator control, NN based human-robot interaction, and NN based cognitive control.

Chairman Hua emphasized in his speech last year at the opening ceremony of the Central Party School that: "Chairman Mao instructed us over and over that ‘the integration of theory and practice is the most fundamental principle of Marxism.’ Chairman Mao fought all his life against the evil work style of boasting and of separating theory from practice. … Political swindlers such as Lin Biao, Chen Boda, and the "gang of four" have messed up many basic theoretical issues and damaged (...) our Party's good learning style. We must make a tremendous effort to correct that.". (shrink)

Discussing the issues of “Asia,” Takeuchi Yoshimi’s discourse of “Overcoming Modernity” has received broad attention among the international community of scholars. Commentators try to identify the ideological elements of this discourse that, as they hope, could help to solve post-modern problems. After analysing Takeuchi’s understanding of the war and its context, this paper shows that his discourse of “overcoming modernity” has an anti-historical tendency, which stems from the ideological ambiguity of his attitude towards the question of who was responsible for (...) the war.

Ten years ago, conceptual history was still relatively unknown in Chinese academic circles. But within just a single decade, it has already emerged as a very popular field among scholars. When broaching conceptual history, the first thing to make clear is that, whether we’re speaking of a research field or a methodology, this is a scholarly tradition rooted in Germany. Hence, if we are to apply conceptual historical methods to China and carry out transcultural conceptual historical research here, we must (...) understand the basic connotations of conceptual history. Reinhart Koselleck’s introduction to 8 volumes of Basic Concepts of History: An Historical Lexicon of Political and Social Terms in Germany is an essential text in conceptual history. In this work, Koselleck proposes three These for conceptual history: concepts are historical, criteria for the “four changes” of basic historical concepts, and the “saddle period.”. (shrink)

If we do not shrink from making rough generalizations and adopt a broad, conventional approach, then what we call modernity refers to the process whereby a state of heterogeneity progresses toward homogeneity in time, space, human collectives, social order, and other areas. In his book The Cheese and the Worms, Carlo Ginzburg discusses a late-16th century incident of heterodoxy that cannot be classified into previously existing standard categories. As new knowledge was disseminated thanks to the invention of the Gutenberg printing (...) press, old and new knowledge came into conflict in the mind of a heterodox figure by the name of Menocchio. He attacked the church, saying that it was more important to love one’s neighbor than to love God. Through these small, humble manifestations of change, Ginzburg was able to reveal the juncture when European modern knowledge first emerged from a muddled, undifferentiated state into one of clarity, whereby over the course of about a century of fermentation, its contours eventually became clearly evident around the year 1800. This process has been termed by the pioneer of conceptual history Otto Brunner as the “threshold era”, and by Reinhart Koselleck as the beginning of the “saddle era”. (shrink)

In general, stimuli that are familiar and recognizable have an advantage of predominance during binocular rivalry. Recent research has demonstrated that familiar and recognizable stimuli such as upright faces and words in a native language could break interocular suppression faster than their matched controls. In this study, a visible word prime was presented binocularly then replaced by a high-contrast dynamic noise pattern presented to one eye and either a semantically related or unrelated word was introduced to the other eye. We (...) measured how long it took for target words to break from suppression. To investigate word-parts priming, a second experiment also included word pairs that had overlapping subword fragments. Results from both experiments consistently show that semantically related words and words that shared subword fragments were faster to gain dominance compared to unrelated words, suggesting that words, even when interocularly suppressed and invisible, can benefit from semantic and subword priming.

Lachlan observed that the infimum of two r.e. degrees considered in the r.e. degrees coincides with the one considered in the ${\Delta_2^0}$ degrees. It is not true anymore for the d.r.e. degrees. Kaddah proved in (Ann Pure Appl Log 62(3):207–263, 1993) that there are d.r.e. degrees a, b, c and a 3-r.e. degree x such that a is the infimum of b, c in the d.r.e. degrees, but not in the 3-r.e. degrees, as a < x < b, c. In (...) this paper, we extend Kaddah’s result by showing that such a structural difference occurs densely in the r.e. degrees. Our result immediately implies that the isolated 3-r.e. degrees are dense in the r.e. degrees, which was first proved by LaForte. (shrink)

What is the criterion of truth? This is a question that was resolved long ago by the revolutionary teachers of the proletariat. But as a result of damage done by the "Gang of Four" and a mass of distorted propaganda in the media under their control, it has become muddled beyond compare in recent years. In order to deepen the criticism of the "Gang of Four" and eradicate the remnants of their poison and influence, it is very important to clear (...) this up and sort it out. (shrink)

Two recent publications highlight the role of bone‐forming cells, the osteoblasts, in controlling the development of neighboring haematopoietic stem cells (HSCs).1,2 Using two distinct transgenic mouse models, one using the conditional deletion of the Bone Morphogenetic Protein Receptor 1A (BMPR1A) gene, the other using over‐expression of an active PTH/PTHrP receptor (PPR) mutant within osteoblasts, the authors show parallel, concordant increases in the generation of trabecular osteoblasts and the number of HSCs. In situ staining showed that rarely cycling HSCs sporadically attach (...) to endosteal osteoblasts, while in vitro assays indicated that ligation of Jag1 on osteoblasts by Notch1 on HSCs promotes HSC proliferation. These two independent works have revived and revitalized the notion that osteoblasts are a major, defining component of the HSC niche within the bone marrow (BM). This minireview discusses these results in the context of other recent studies of mesenchymal cells within the BM microenvironment, presents one potential unified model of the functional anatomy of the BM HSC niche, and highlights new questions raised by these and other studies of osteoblasts and HSCs.

The yin yang model of thinking is most essential to the Chinese cosmology, ontology and outlook on life. This paper is a systematic discussion of such a dialectical way of thinking and its significance. It starts with investigating the origin and the meaning of terms “yin” and “yang”, and explains the later developed yin yang doctrine; it then shows how greatly and profoundly the yin yang model of thinking has influenced Chinese philosophy and Chinese character. It concludes that Chinese naturalistic, (...) dialectical, and optimistic attitudes toward the world and life are all based on the yin yang model of thinking and that the yin yang doctrine is the starting point for anyone to understand Chinese people and their philosophies.
