Receptor tyrosine kinases and integrins are activated by growth factors and extracellular matrix, respectively. Their activation leads to signal transduction cascades that control many aspects of cell phenotype, including progression through the G1 phase of the cell cycle. However, the signalling cassettes driven by growth factors and matrix do not work independently of each other. Integrin triggering is essential to facilitate kinase‐ and GTPase‐mediated signals and thereby drive efficient transfer of information through the growth factor–cyclin axis. A recent study indicates (...) that an additional type of player has a key role in adhesion‐regulated control of cell cycle, namely ubiquitin ligase.(1) BioEssays 24:17–21, 2002. © 2002 John Wiley & Sons, Inc.

This qualitative research focuses on Dong's Wind and Rain Bridges in Chengyang Bazhai in Liuzhou, China. This research explores the academic issue of public space and meaning change in the process of minority development, through the Dong's Wind and Rain Bridges phenomenon. The findings of this research are that public space in all societies in the world is a fusion of space production and meaning and constructs identity and social relations. It has changed in the context of the times and (...) has produced new functions for different groups of people, constantly generating new meanings superimposed on the old meanings. As an important public space in the community, Dong's Wind and Rain Bridges include the physical space production of the surrounding area and the social and mental space production of the Dong ethnic group, emphasizing the close relationship between "space production" and "ethnic identity". In the process of minority development in China, the use of the wind and rain bridge's public space has changed socially, responding to the new needs of different groups. It, therefore, has been constantly undergoing "meaning change". (shrink)

PurposeTo investigate spontaneous brain activity in patients with dry eye and healthy control using the fractional amplitude of low frequency fluctuation technique with the aim of elucidating the relationship between the clinical symptoms of DE and changes in brain function.Material and MethodsA total of 28 patients with DE and 28 matched healthy volunteers were enrolled. Resting-state functional magnetic resonance imaging scans were performed in both groups. Then all subjects were required to complete a comprehensive Hospital Anxiety and Depression Scale. Receiver (...) operating characteristic curve analysis was used to evaluate the differences in fALFF values between the two groups and their diagnostic value. Linear correlations between HADS and fALFF values in different brain regions of DE patients were analyzed using the Pearson correlation coefficient.ResultsPatients with DE had significantly higher fALFF values in the left calcarine sulcus than the HC group, while fALFF values in the bilateral middle frontal gyrus and right MFG/right inferior frontal gyrus were significantly lower in DE patients than in HC group. fALFF values had a high diagnostic value for differentiating patients with DE from the HC group. Right MFG and right MFG/IFG were significantly correlated with HADS values.ConclusionOur study found that DE mainly involved functional disorders in the brain areas of the left CS, bilateral MFG and right MFG/right IFG, which helped us to find possible clinical features of DE disease and reflected the potential pathological mechanism of DE.

Chinese medicine has a history of at least 2,000 years. The first explicit literature on medical ethics did not appear until the seventh century when a physician named Sun Simiao wrote a famous treatise titled “On the Absolute Sincerity of Great Physicians” in his work The Important Prescriptions Worth a Thousand Pieces of Gold. In this treatise, later called The Chinese Hippocratic Oath, Sun Simiao required the physician to develop first a sense of compassion and piety, and then to make (...) a commitment to try to save every living creature, to treat every patient on equal grounds, and to avoid seeking wealth because of his expertise.

The Chinese public medical care system was established after the 1949 revolution. However, there is no necessary connection between Marxism and the public medical care system; and although the current system may be reasonable from an historical point of view, it can no longer be justified ethically as an all-embracing medical system, since it does not provide equitable health care for the people.

Scholarly interest in employees’ voluntary pro-environmental behavior has begun to emerge. While this research is beginning to shed light on the predictors of workplace pro-environmental behavior, our understanding of the psychological mechanisms linking the various antecedents to employees’ environmentally responsible behavior and the circumstances under which any such effects are enhanced and/or attenuated is incomplete. The current study seeks to fill this gap by examining: the effects of perceived corporate social responsibility on employees’ voluntary pro-environment behavior; an underlying mechanism that (...) links CSR perceptions to these behaviors; and a boundary condition to these relationships. Data from 183 supervisor-subordinate dyads employed in large- and medium-sized casinos and hotels in Guangdong China and Macau revealed that employees’ corporate social responsibility perceptions indirectly affect their engagement in voluntary pro-environmental behavior through organizational identification, and these effects are stronger for employees high in empathy.

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)

A multiphase study tested a proposed mediated moderation model for the joint effects of ethical pressure and power distance orientation on accountants’ ethical judgments of earnings management. Results based on a sample of 354 accountants from China indicated that the relationship between ethical pressure and ethical judgments of earnings management is contingent on the accountants’ power distance orientation. That is, the relationship between ethical pressure and ethical judgments of earnings management was stronger for accountants with a high power distance orientation. (...) The results also demonstrated that ethical beliefs in support of the company serve as a mediator for the interaction effect of ethical pressure and power distance orientation on the outcome. These results are discussed in terms of viewing earnings management as a form of unethical pro-organizational behavior which can be effectively investigated within the framework of the person-situation interactionist model.

This paper examines the impact of Chinese business managers’ moral philosophies on the perception of corrupt payments such as bribery, kickbacks and gift giving. Business managers from Mainland China were selected as target respondents. As hypothesized the survey results generally indicate that moral relativism is a significant predictor of Chinese business managers’ favorable perception of bribery and kickbacks. In examining the attitude toward gift giving, the survey showed that an individual’s attitude toward gift giving was neither affected by their moral (...) relativism nor by their moral idealism, which implies that gift giving is widely accepted as legal practice in business in Chinese cultural society.

The teaching management department carries all the work related to teaching in the whole school. A scientific, efficient, and complete teaching management system cannot only help the teaching management department improve work efficiency and quality but also greatly reduce many problems caused by manual labour risk. This paper designs and implements a teaching management system based on an improved association rule algorithm. First, aiming at the low efficiency of the Apriori algorithm for mining association rules, an association rule model based (...) on interest is proposed. Second, use the MapReduce calculation model to partition the transaction database, then use the improved Apriori optimization algorithm for mining, and finally merge the mining results to obtain frequent itemsets. Through experiments, the optimized algorithm has greatly improved selection mining and computing time than traditional algorithms. (shrink)

This study investigated the internal mechanism of the relationship between primary school students’ peer relationships and their performance in the Chinese language and literature. We constructed a chain mediation model, focused on the mediation effects of parental involvement and the sense of autonomy, on the correlation between peer relationships and performance in Chinese language scores. A questionnaire survey was conducted among 1,503 students in grades 4–6, and their parents, in three cities in Jiangsu Province. The result indicated the following: there (...) was a significant positive correlation between primary school students’ peer relationships, parental involvement, sense of autonomy, and the level of Chinese language scores; parental involvement and the sense of autonomy, respectively, mediate the relationship between peer relationships and Chinese language scores; primary school students’ parental involvement and sense of autonomy play a chain-like mediating role in the relationship between their peer relationships and Chinese language scores. The research results provide a reference for exploring the educational strategies of primary school students’ Chinese literacy. (shrink)

One of the most significant challenges in the application of brain-computer interfaces is the large performance variation, which often occurs over time or across users. Recent evidence suggests that the physiological states may explain this performance variation in BCI, however, the underlying neurophysiological mechanism is unclear. In this study, we conducted a seven-session motor-imagery experiment on 20 healthy subjects to investigate the neurophysiological mechanism on the performance variation. The classification accuracy was calculated offline by common spatial pattern and support vector (...) machine algorithms to measure the MI performance of each subject and session. Relative Power values from different rhythms and task stages were used to reflect the physiological states and their correlation with the BCI performance was investigated. Results showed that the alpha band RP from the supplementary motor area within a few seconds before MI was positively correlated with performance. Besides, the changes of RP between task and pre-task stage from theta, alpha, and gamma band were also found to be correlated with performance both across time and subjects. These findings reveal a neurophysiological manifestation of the performance variations, and would further provide a way to improve the BCI performance. (shrink)

The underrepresentation of females on corporate boards is an important ethical issue that raises serious concerns about gender equality in senior management teams. Relying on a large sample of public firms from the Chinese market, we examine how social trust affects female board representation. We find that female board representation has a positive and significant relation with social trust. The effect is more pronounced in regions with a higher male-to-female sex ratio at birth, lower levels of education, lower GDP per (...) capita, and in nonfamily firms. We also find that higher social trust is more likely to increase the number of non-independent female directors rather than independent ones. Further analyses show that increased female board representation is an important channel through which social trust improves corporate ESG ratings. Overall, our study suggests that social trust contributes positively to gender diversity in corporate management. (shrink)
