This article starts with the analysis of the existing electronic commerce system, summarizes its characteristics, and analyzes and solves its existing problems. Firstly, the characteristics of the relational database My Structured Query Language and the distributed database HBase are analyzed, their respective advantages and disadvantages are summarized, and the advantages and disadvantages of each are taken into account when storing data. My SQL is used to store structured business data in the system, while HBase is used to store unstructured data (...) such as pictures. These two storage mechanisms together constitute a data storage subsystem. Secondly, considering the large amount of data in the e-commerce system and the complex calculation of the data mining algorithm, this paper uses MapReduce to realize the parallelization of the data mining algorithm and builds a Hadoop-based commodity recommendation subsystem on this basis. We use JavaEE technology to design a full-featured web mall system. Finally, based on the impact of cloud computing, mobile e-commerce is analyzed, including relevant theories, service mode, architecture, core technology, and the application in e-commerce, which can realize e-commerce precision marketing, find the optimal path of logistics, and take effective security measures to avoid transaction risks. This method can avoid the disadvantages of the traditional e-commerce, where large-scale data cannot be processed in a timely manner, realize the value of mining data behind, and realize the precision marketing of e-commerce enterprises.

Atomic-scale computer simulation has been used to study the thermally activated atomic transport of self-interstitial atoms in the form of planar clusters in pure Cu and f -Fe. There is strong evidence that such clusters are commonly formed in metals during irradiation with high-energy particles and play an important role in accumulation and spatial distribution of surviving defects. An extensive study of the mobility of SIA clusters containing two to 331 interstitials has been carried out using the molecular dynamics simulation (...) technique for the temperature range from 180 to 1200 K. The results obtained show that clusters larger than three to four SIAs are one-dimensionally mobile in both Cu and Fe. Large clusters of more than 100 SIAs in Cu and 300 SIAs in Fe have significantly reduced mobility. The problem of describing one-dimensional motion in three-dimensional space is discussed. An attempt is made to describe the mobility of SIA clusters within the approximation of 1D diffusion. For clusters in both metals the effective migration energy of 1D diffusion as estimated via the jump frequency of the cluster centre of mass is found to be independent of the number of SIAs in the clusters, although the cluster jump frequency decreases with increasing cluster size. Mechanisms of 1D mobility of interstitial clusters are discussed. (shrink)

Machery et al. presented data suggesting the existence of cross-cultural variation in judgments about the reference of proper names. In this paper, we examine a previously overlooked confound in the subsequent studies that attempt to replicate the results of Machery et al. using East Asian languages. Machery et al. and Sytsma et al. claim that they have successfully replicated the original finding with probes written in Chinese and Japanese, respectively. These studies, however, crucially rely on uses of articleless, ‘bare noun (...) phrases’ in Chinese and Japanese, which according to the linguistic literature are known to be multiply ambiguous. We argue that it becomes questionable whether the extant studies using East Asian languages revealed genuine cross-cultural variation when the probes are reevaluated based on a proper linguistic understanding of Chinese and Japanese bare noun phrases and English definite descriptions. We also present two experiments on native Japanese speakers that controlled the use of ambiguous bare noun phrases, the results of which suggest that the judgments of Japanese speakers concerning the reference of proper names may not diverge from those of English speakers.

Speech categories are defined by multiple acoustic dimensions and their boundaries are generally fuzzy and ambiguous in part because listeners often give differential weighting to these cue dimensions during phonetic categorization. This study explored how a listener's perception of a speaker's socio-indexical and personality characteristics influences the listener's perceptual cue weighting. In a matched-guise study, three groups of listeners classified a series of gender-neutral /b/-/p/ continua that vary in VOT and F0 at the onset of the following vowel. Listeners were (...) assigned to one of three prompt conditions and rated the talker in terms of vocal gender prototypicality, attractiveness, friendliness, confidence, trustworthiness, and gayness. Male listeners and listeners who saw a male face showed less reliance on VOT compared to listeners in the other conditions. Listeners' visual evaluation of the talker also affected their weighting of VOT and onset F0 cues, although the effects of facial impressions differ depending on the gender of the listener. The results demonstrate that individual differences in perceptual cue weighting are modulated by the listener's gender and his/her subjective evaluation of the talker. These findings lend support for exemplar-based models of speech perception and production where socio-indexical features are encoded as a part of the episodic traces in the listeners' mental lexicon. This study also shed light on the relationship between individual variation in cue weighting and community-level sound change by demonstrating that VOT and onset F0 co-variation in North American English has acquired a certain degree of socio-indexical significance.

The simplest nonlinear spinor field equation admitting regular stationary solutions is considered. Following a causal interpretation of quantum mechanics, given by de Broglie in his double solution theory, these regular solutions must be regarded as describing the internal particle structure. Using this spinor field model, an attempt is made to give a statistical description of one-particle experiments by means of a Gibbsian assemblage method. It is shown that in the limiting case of pointlike nonrelativistic particles this method is equivalent to (...) the quantum mechanical one, that is, the probability amplitude can be introduced satisfying all postulates of quantum mechanics.

Yuan Dynasty was an era with austere political reality and thinking reality. As a result of despisement to ruling of different races, a large majority of scholars in Yuan Dynasty chose seclusion without other choice, but the “internal beauty” they pursued was amazingly unanimous, which was, without doubt, owing to the spirit of the mountains and forests. When they tried to find enjoyment in painting, they put their willpower in it, which was a spontaneous awareness of cultural spirit and was, (...) moreover, a peak experience of Chinese traditional culture. Achievement of Yuan Dynasty painting was impressive, and extended the aesthetic space of human beings. Thus, it enriched and development and manifestation connotation of landscape painting to a great extent, and would be engraved forever in the spiritual and cultural history of human beings. (shrink)

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)

Since the 1950s, Lee Joseph of Zhu Xi of the Road, learn to criticism that many aspects of Taoism is similar to Whitehead's qualification process philosophy, which Zhu large amount of philosophical comprehensive work is the right assessment, triggering In order to controversy . This paper argues that there are many real reason is that Zhu and Whitehead都qualification processes philosopher. According to Whitehead's thought, emphasizing the role or function of qualifications process description is the qualification process may philosopher. Zhu Xi (...) said in his clear emphasis on learning裡qualification process, change, transformation and innovation of other concepts. Description of this method less controversial, but the problem is in the end "qualification process" concept in terms of how important Zhu? He has "qualification process" concept is obvious? Over the past eight hundred years have an ongoing controversy, Zhu Xi Road School for the qualification process as the subject is so obvious? Zhu Xi describes the nature of the universe is life and life does not interest, is well known. However, many scholars have argued Zhu Xi's description of the main school - "Management", or the original management, channel management, pattern, or order, in fact, is a static concept. If "management" is static or just the original order or pattern in the form of management, it is difficult to establish qualification process is a description of the key themes of philosophy. Like a dead Yuzhe how it is possible to control a horse living ? This is a serious topic, in fact, followed by South Korean scholars to discuss the subject, which launched the great "forty-seven Debate." This article will certainly "reasonable" can indeed be interpreted as a life principle of management by a manager or management Concept. Really the case, said Zhu Xi's learning can rightly be regarded as a strongly significant qualification process philosophy, such as Whitehead and Lee Snow and other scholars advocated. Zhu Xi to provide In order many of the "reasonable" interpretation, possible these things in the world or the events of the original treatment or reason, interpreted with the qualification process in nature, even creative, with its complex of Taoist system role. This will be Chen Chun highly influential book of the "North Creek word meaning" to prove the wisdom of philosophy of Zhu Xi's disciples will be the most "reasonable" as a "way of qualifications." Therefore, based on an important school of Zhu Xi's interpretation of Taoism, we can agree and support the Joseph Lee, Zhu Xi Neo-Confucianism as the philosophy of the Core see qualification process. Ever since Joseph Needham in the 1950s made the comment that in many ways the daoxue of Zhu Xi resembled the process philosophy of Alfred North Whitehead there has been a debate on whether or not this is an accurate assessment of the Master Zhu's massive philosophical synthesis. This paper argues that there are substantive grounds to suggest that both Master Zhu and Whitehead are process philosophers. Based on Whitehead's observation that some philosophers emphasize the role or function or process as a key element of their philosophical vision and hence can be deemed 'process' philosophers, it is clear that Zhu certainly affirmed a central place for notions of process, change, transformation and creativity within his daoxue or Teaching of the Way. In many ways there is little argument about the general nature of this comment: the problem is, just how central to Zhu's daoxue is the notion of process? Is process more apparent than real? There has been a constant debate for the last eight hundred years as to whether or not Zhu Xi's commitment to process as a central theme or motif of daoxue is as strong as it appears at first glance. Zhu was famous for saying that the nature of the cosmos is, for instance, constant generation or shengsheng buxi life and life does not interest rates. Nonetheless, many competent scholars have argued that Zhu's crucial notion of li management or principle, rationale, pattern, or order might actually be a static concept: hardly the kind of key theme to build a process philosophy around if indeed it is the case that principle is a static or merely a formal principle of order or pattern . One of the best ways of putting the question was, how can a dead rider ride a live horse ? This is a serious question, and in fact later Korean scholars debated the issue with great subtlety in the great Four-Seven Debate. This paper will defend the notion that li can indeed be interpreted as a living principle or rationale. If this is the case, then Zhu's daoxue can be rightly deemed a process philosophy in the strongest sense of the term as defined by scholars such as Whitehead and Nicholas Rescher. Although Zhu Xi offered a number of different interpretations of li, it is entirely plausible that principle or the rationale for the things and events of the world can be construed as processive, even creative in terms of its role in the complex daoxue architectonic. For instance, the influential Beixi ziyi [or Neo-Confucian Terms Explained as translated by Wing-tsit Chan] of Chen Chun proves that one of Master Zhu's most philosophically astute disciples understood li to be proccessive. Therefore, based on one important stream of exegesis of Zhu's daoxue, we can agree with and support Joseph Needham's insight that daoxue is a form of process philosophy. (shrink)

To investigate the phenomenon of patient–physician mistrust in China, a qualitative study involving 107 physicians, nurses and health officials in Guangdong Province, southern China, was conducted through semi-structured interviews and focus groups. In this paper we report the key findings of the empirical study and argue for the essential role of medical professionalism in rebuilding patient-physician trust. Health professionals are trapped in a vicious circle of mistrust. Mistrust leads to increased levels of fear and self-protection by doctors which exacerbate difficulties (...) in communication; in turn, this increases physician workloads, adding to a strong sense of injustice and victimization. These factors produce poorer healthcare outcomes and increasingly discontented and angry patients, escalate conflicts and disputes, and result in negative media coverage, all these ultimately contributing to even greater levels of mistrust. The vicious circle indicates not only the crisis of patient-physician relationship but the crisis of medicine as a profession and institution. Underlying the circle is the inherent conflict of interest in the healthcare system by which health professionals and hospitals have become profit-driven. This institutional conflict of interest seriously compromises the fundamental principle of medical professionalism—the primacy of patient welfare—as well as the traditional Chinese ideal of “medicine as the art of humanity”. Patient trust can be restored through rectifying this institutional conflict of interest and promoting medical professionalism via a series of recommended practical measures. (shrink)

Our understanding of the cognitive processes involved in reading has been advanced by computational models that simulate those processes. Unfortunately, most of these models have been developed to explain the reading of English and other alphabetic languages, with relatively fewer efforts to examine whether or not the assumptions of these models also explain what has been learned from other languages and, in particular, non-alphabetic writing systems like Chinese. In this article, we will review those computational models that have been developed (...) to explain the reading of Chinese, with the goal of comparing their theoretical assumptions to those of models that explain the reading of English. Our analysis indicates that there are both points of convergence and divergence between the theoretical assumptions of Chinese versus English models, suggesting that the cognitive systems supporting reading may be differentially influenced by features of the languages and/or writing systems, or that certain theoretical assumptions developed to explain the reading of one language might be adapted to explain the reading of others.

Atmospheric pollution is deteriorating, which has affected the evolution of respiratory disease for the exposed human worldwide. Thus, exploring the influence of air pollution on the evolution of disease transmission dynamics is a significant issue. In this article, a stochastic susceptible-infective epidemic model in a polluted atmospheric environment is investigated. The existence and uniqueness of the global positive solution are established. In virtue of the aggregation methods and Lyapunov function, the sufficient conditions of disease extinction, persistence, and existence of the (...) stationary distribution are established, respectively. TakingPM2.5concentration as the air pollutant index, numerical simulations are carried out to support these results. Our results indicated that the disease transmission dynamics are significantly associated with the environmental atmospheric pollution and fluctuation. (shrink)

The ring‐shaped ATPase machine, cohesin, regulates sister chromatid cohesion, transcription, and DNA repair by topologically entrapping DNA. Here, we propose a rigid scaffold model to explain how the cohesin regulators Pds5 and Wapl release cohesin from chromosomes. Recent studies have established the Smc3‐Scc1 interface as the DNA exit gate of cohesin, revealed a requirement for ATP hydrolysis in ring opening, suggested regulation of the cohesin ATPase activity by DNA and Smc3 acetylation, and provided insights into how Pds5 and Wapl open (...) this exit gate. We hypothesize that Pds5, Wapl, and SA1/2 form a rigid scaffold that docks on Scc1 and anchors the N‐terminal domain of Scc1 (Scc1N) to the Smc1 ATPase head. Relative movements between the Smc1‐3 ATPase heads driven by ATP and Wapl disrupt the Smc3‐Scc1 interface. Pds5 binds the dissociated Scc1N and prolongs this open state of cohesin, releasing DNA. We review the evidence supporting this model and suggest experiments that can further test its key principles. (shrink)
