We evaluated an advanced forward-modeling-based reservoir characterization technique that uses full elastic finite-difference simulation to investigate the limits of karst identification in stacked seismic data. Identification of karsts is important for field development in carbonated reservoirs because paleokarst features can result in a loss of circulation and/or sometimes lost drill bits. Our primary objective was to verify whether we can detect and interpret the location and size of karsts from seismic data, especially given a complex overburden. We constructed an elastic (...) reservoir model consisting of compressional velocity, shear velocity, and density for the study area using interpreted horizons and well log information. Karsts with varying widths, thicknesses, dip angles, and porosities were inserted to generate multiple versions of the model. We also evaluated the imaging impact of overlying faults and salt on karst detection. Full elastic simulation was performed on the various reservoir models using a realistic acquisition geometry to generate gathers, which were then prestack time migrated to quantify the impact of different karst properties on the seismic images and study the effect of reservoir property changes on the seismic response. Finally, a wave-equation target-oriented analysis was presented to improve the understanding of subsalt amplitude and illumination. From the finite-difference modeling and analysis that we performed, we obtained an uncertainty range on karst property estimation from seismic images and gained insights into future survey design for subsalt interpretation and amplitude analysis. For our specific model, we found the limit of karst identification from seismic data is a 30-m-wide horizontal karst or a 500 m karst dipping at 60°. Also, the karst image width reflected its true width only when the actual karst width was larger than the P-wave wavelength. With a dipping overburden above the reservoir, apparent positions of karsts were shifted in the updip direction by prestack time migration up to 50 m from their true position. This lateral uncertainty should be kept in mind in well planning to avoid karst features interpreted from a time-migrated seismic section. (shrink)

The results of our research, obtained from a survey of 50 Western managers working in Romania, show that differences exist between Western managers' ethics and those of their Romanian counterparts, especially with regard to bribery. Different backgrounds are at the basis of such divergence. Beyond the communist era and its heritage, the cultural aspect of bribery has been analyzed. Nevertheless, the results of our research suggest that culture may play a double role and the influence could come from both the (...) home environment of Western managers and their new environment. Some Western managers who adapt to the Romanian environment appear to have been already conditioned to bribery from their home environment. (shrink)

Taking the increasing implementation and practice of ?quality?oriented education? as the background to the current reform, the paper outlines moral education in the Chinese junior high school over the last 25 years. It offers a brief review of a few theoretical and empirical research projects which have had some influence on the 2003 reform of the course of Ideology and Morality. It describes: three basic principles behind this new curriculum, focusing on the developing lives of students; curriculum characteristics with ideological, (...) humanistic, practical and integrative dimensions; and the objectives of developing feelings, attitudes and value orientations, competencies and knowledge. The curriculum is illustrated by four textbook and class?based examples of respect for parents, self?esteem, environmental awareness and being a responsible citizen, which offer some insights into contemporary moral education with distinctive Chinese characteristics. Finally, the paper gives an overview of the significance of the moral education curriculum reform and of its ongoing challenges. (shrink)

Alzheimer's disease is the most common form of dementia that gradually disrupts the brain network to impair memory, language and cognition. While the amyloid hypothesis remains the leading proposed mechanism to explain AD pathophysiology, anti-amyloid therapeutic strategies have yet to translate into useful therapies, suggesting that amyloid β-protein and its precursor, the amyloid precursor protein are but a part of the disease cascade. Further, risk of AD can be modulated by a number of factors, the most impactful being the ɛ4 (...) isoform of apolipoprotein E. A recent study reported a novel isoform-dependent transcriptional regulation of APP by apoE. These interesting new results add to the myriad of mechanisms that have been proposed to explain how apoE4 enhances AD risk, highlighting the complexities of not only apoE and AD pathophysiology, but also of disease itself. Also see the video abstract here: https://youtu.be/yd14MBdPkCY APP transcription is differentially modulated by apoE and its isoforms: how does this novel mechanism fit with the existing hypotheses?

This study employs the social quality approach to analyze public evaluation of society in China based on the data of the 2017 Chinese Social Survey. It includes both objective and subjective survey indicators of the conditional factors of social quality, namely, socioeconomic security, social cohesion, social inclusion, and social empowerment, as independent variables. Regression results reveal most of these indicators are significantly related to the overall evaluation of society though with different explanatory power. This study not only helps understand how (...) Chinese people evaluate their society but also calls attention to further improve social quality indicator system. (shrink)

The present study examined the behavioral effects of the first-person possessive pronoun. In each trial, a noun was presented to participants after visual presentation of a possessive pronoun “wo de” or “ta de” , which formed ownership. Half participants were assigned to contextual encoding condition in which they were required to judge whether they liked the item expressed by a noun from the first or third-person perspective. The rest were assigned to perceptual encoding condition in which they were asked to (...) judge what color the noun was. A subsequent recall test was performed. The results showed that there were significant memory and response advantages for nouns in “my” ownership under both conditions. The results were discussed with reference to self-specificity and other effects in the current study. (shrink)

Agricultural enterprises play a significant role in China’s economic development. However, compared with other enterprises, agricultural enterprises are facing serious financial problems. Financing difficulty is essentially a question of financing efficiency. Based on the DEA method, this paper evaluates the financing efficiency of 39 agricultural listed companies in China from 2013 to 2017. The results suggest that the financing efficiency is generally low, and the Total Factor Productivity of agricultural enterprises’ financing has a tendency to decrease first and then increase. (...) The influencing factors of financing efficiency are analyzed using the Tobit regression model and the random forest regression model. And we find the following: The random forest regression model significantly outperformed the Tobit regression model, with determination coefficients greater than 0.9 in full sample sets. Total liability, financial expenses, return on total assets, and inventory turnover rate are important factors affecting financing efficiency of agricultural listed companies. Return on total assets and inventory turnover rate promote the financing efficiency, while total liability and financial expenses reduce financing efficiency. Finally, the paper makes some suggestions for the financing of agricultural enterprises. (shrink)

Zhan Ruoshui 湛若水 is a prominent scholar-official and Confucian philosopher of Ming China. Like his contemporary Wang Yangming, he served in several official capacities during the reigns ofthree mid-Ming emperors, earned a reputation as an important Confucian teacher, gained a substantial following of students, and was critical to the onset of the jiangxue 講學 movement of the mid-Ming and the academy building associated with it. He also elaborated a sophisticated Confucian philosophy, leaving behind a corpus of work and a (...) school of thought. In 1517, when he was fifty-one, Zhan Ruoshui left office and retired to Mount Xiqiao 西樵山 in Guangdong, where he constructed both a hermitage for his family and an academy for his students. He remained there for four years until he was recommended for reappointment to office in 1521. These years were critical not only for his having established his first academy and writing the regulations for operating it but also because he produced a substantial volume of philosophical writings that were foundational to his becoming recognized as a Confucian master and establishing his school of thought. This study provides an overview of the biographical and historical setting, Zhan’s pedagogy, and his philosophy at a time when this lesser-known Ming Confucian passed through a crucial stage in the development of his Way.

Travel route preferences can strongly interact with the events that happened in networked traveling, and this coevolving phenomena are essential in providing theoretical foundations for travel route recommendation and predicting collective behaviour in social systems. While most literature puts the focus on route recommendation of individual scenic spots instead of city travel, we propose a novel approach named City Travel Route Recommendation based on Sequential Events Similarity by applying the coevolving spreading dynamics of the city tour networks and mine the (...) travel spatiotemporal patterns in the networks. First, we present the Event Sequence Similarity Measurement Method based on modelling tourists’ travel sequences. The method can help measure similarities in various city travel routes, which combine different scenic types, time slots, and relative locations. Second, by applying the user preference learning method based on scenic type, we learn from the user’s city travel historical data and compute the personalized travel preference. Finally, we verify our algorithm by collecting data of 54 city travellers of their historical spatiotemporal routes in the ten most popular cities from Mafeng.com. CTRR-SES shows better performance in predicting the user’s new city travel sequence fitting the user’s individual preference. (shrink)

Xunzi carried on the noble ambitions of “Zhou Kong Jiaohua 周孔教化” and systematically demonstrated the necessity of cultivation and how to realize it. Starting from the belief that human nature is evil, he argues that cultivation was necessary and its teachings must penetrate the mind. The key of cultivation is to cultivate man’s feelings, encourage man to behave properly, and attempt to mold his nature through Ritual cultivation, Musical cultivation, and the Five Classics. The main point of Xunzi’s ethical thought (...) is cultivation. As far as cultivation theory is concerned, Xunzi’s is the most logical and systematic of the famous Pre-Qin thinkers. (shrink)

The article is of the opinion that simultaneous with the study of practice as an aggregate that conditions the movement of knowledge an in-depth inquiry should be made into the structure and function of practice and its law of development from different angles. The article lays emphasis on probing into the following: the process in which the capacity for practice is converted from potential into reality and the specific social and historical conditions for the conversion; the dialectic relations between the (...) purpose and effect, the effect and efficiency, and the general and the partial effect of practice and the objective criterion to judge the effect; and the feedback mechanism of the movement of practice and its function. On the basis of the above, the article analyzes the intricate interactions between practice and its various links of efficacy, effect, and feedback and arrives at the conclusion that the dialectical cycle of "practice-efficacy-effect-feedback-practice" is objective, universal, dynamic, and open and thus constitutes one of the basic laws of the movement of practice.
