Cangdong is a typical oil-rich sag in the Bohai Bay Basin, China. After more than 50 years of exploration and development, the Kong2 Member still has considerable residual oil and gas resource potential. To pursue replacement areas of oil and gas exploration and development, the basic geology of the entire Kong2 Member in Cangdong Sag as a unit has been reexamined, and the findings have been used to guide the secondary exploration deployment. In this study, the characteristics of sedimentary reservoirs, (...) source rocks, and oil and gas distribution in the Kong2 Member have been systematically studied, and a sedimentary model of the ring belt-circle layer of the closed lake basin in the Kong2 Member of the Cangdong Sag, with three segments on the profile, three ring belts on the plane, and three circle layers in space has been established. The ring belt and circle layer are jointly controlled by water-body differentiation in the closed lake basin, source-material supply, depositional accommodation space, and deposition base-level cycle, and they can be in round, oval, long strip, and irregular shapes. The outer ring, located near the basin margin, mainly has delta-front subfacies conventional coarse-grained medium-thick sandstone and near-source structural and stratigraphic-lithologic reservoirs; the middle ring, the transitional zone from the basin margin to the central basin, is dominated by fine sandstone, siltstone, and lacustrine carbonates of front delta subfacies, and it mainly contains isolated lithologic reservoirs and unconventional tight oil; the inner ring is the high-quality hydrocarbon source-rock development zone in the center of the closed lake basin, featuring a high abundance of shale, where the dolomite and siltstone of distal gravity flow right next to source rock, and fine-grained diamictite of the source reservoir in one area rich in tight oil, whereas the high-abundance shale of frequent source-reservoir interbeds is rich in shale oil. The strategy of oil and gas exploration deployment is to look for structural, stratigraphic-lithologic reservoirs in the outer circle, lithologic reservoirs in the middle circle, and retained tight oil and shale oil in the inner ring. In recent years, major discoveries have been made in oil and gas exploration in the three circle layers of the Kong2 Member in the Cangdong Sag through drilling, especially in tight-oil exploration in the inner-circle layer: two sandstone sweet-spot intervals of greater than 60 m and three dolomite sweet-spot intervals of greater than 100 m have been confirmed. The maximum daily oil production of vertical wells after fracturing is up to 50 t; several hundred square kilometers of favorable exploration area has been delineated, with an estimated oil geologic resource of 100 million tons.

This paper is a study of Lik Lu Pu Khwan Khao, a chant used in the worship ceremony to the god of rice Pu Khwan Khao of Dehong Tai in Yunnan. The ceremony is performed after the harvest to express gratitude to Pu Khwan Khao. Related ceremonies are found among other groups of Tai peoples. The ceremony is related to the rice myth of Dehong Tai in which Pu Khwan Khao claimed that his merit was comparable with that of the (...) Buddha since nobody could stay alive without him, including the Buddha who could attain awakening only after consuming rice. The Buddha accepted this claim and told people not forget to worship Pu Khwan Khao. The myth reflects a compromise between ancient Tai belief and Buddhism. However, the compromise between and combining of these two sets of belief are also expressed in the Lik Lu Pu Khwan Khao chant. People express their gratitude to Pu Khwan Khao for providing them with rice, not only for nourishment but also for giving alm to monks, one of the most significant practices in Buddhism. Moreover, when people present offerings to Pu Khwan Khao, they form the aspiration to be reborn in the time of the future Buddha, Maitreya, and to attain Nirvana after listening to him preach. This traditional aspiration shows how the ancient ritual of Pu Khwan Khao worship is now intrinsically associated with the Buddhist practice of generosity as a kind of gift giving. From this we may conclude that, for the Dehong Tai in Yunnan, the aim of Pu Khwan Khao worship is not only fertility but also the ultimate Buddhist felicity, Nirvana. (shrink)
Euthanasia in China is gaining increasing acceptance among physicians, intellectuals, and even the people. This paper surveys current attitudes towards euthanasia and suggests why it should be legalized.
This study uses a rational ethical decision-making framework to examine the influence of moral intensity (potential harm and social pressure) on whistleblowing intention and behaviour using organisational commitment as a moderator. A scenario was developed, and an online questionnaire was used to conduct an empirical analysis on the responses of 533 participants. The mean age and years of work experience of the respondents were 31 and 8.2 years, respectively. The results show, first, that while moral intensity is correlated with whistleblowing (...) intention, only the potential harm is positively correlated with such intention. Second, potential harm and social pressure differentially affect whistleblower choice of using an internal or external channel. Third, organisational commitment has a moderated mediation effect among moral intensity, whistleblowing intention and behaviour. Fourth, whistleblowers may be grouped into four conceptual types: indifferent, rebel, mature and spoil. Finally, theoretical and managerial implications of the findings are discussed. (shrink)
The prosperous development of online education in the digital age harvested countless consumers. Education for sustainable development is an important proposition for both academic community and practitioner, however, current little studies have shed light on Sustainable Consumption Behavior in online education industry. The Consumer Value Theory and Social Identity Theory as theoretical basis linked with the field of Sustainable Consumption Behavior. This study is to further investigate the role of consumer value and social identity in the relation to Sustainable Consumption (...) Behavior. Putting forward suggestions from this study to online education providers toward sustainable development.MethodData on the impact of personal value on SCBOEI through a survey method with 552 valid students as respondents are collected from higher education institutions in China. A structural equation modeling approach is employed in this study for data analysis.ResultsThe result shows at the level of excellent model fit as indicated by all indicators: X2/DF = 1.053. The results showed that, through social identity, functional value, emotional value, and social value influence the variance of SCBOEI. The finding reveals that both theories can explain the SCBOEI of higher education students by showing that functional, social, and emotional values as well as social identity are powerful predictors of the Sustainable Consumption Behavior. The proposed model highlights the mediating role of social identity between SCBOEI and the three values. The functional, emotional, and social values influence SCBOEI directly and through social identity.ImplicationsThe study significantly contributes to market promotion, college students, education planning, and teaching. Online education market personnel and college students can better understand the significance of sustainable development aspect of online education. Teaching and learning activities help lead students to SCBOEI by shaping their values and identities while paying more attention to quality education, knowledge sharing, and social equality. (shrink)
Sydney Shoemaker argues that a certain class of self-ascriptions is immune to error through misidentification relative to the first-person pronouns. In their “Self-Consciousness and Immunity,” Timothy Lane and Caleb Liang question Shoemaker’s view. Lang and Liang present a clinical case and an experiment and argue that they are counterexamples to Shoemaker’s view. This paper is a response to Lane and Liang’s challenge. I identify the desiderata that a counterexample to Shoemaker’s view must meet and show that somatoparaphrenia and the Body (...) Swap Illusion fail to meet those desiderata. Thus, despite being puzzling phenomena, somatoparaphrenia and the Body Swap Illusion are not counterexamples to Shoemaker’s view. (shrink)
In October 1993, a cache of bamboo slips written in the Chu script was excavated from a Warring States period tomb in the village of Guodian in the city of Jingmen in the province of Hubei. After separation and arrangement by experts, the photo plates of the Chu slips and their annotations were published this May by Wenwu Press in the book called Guodian Chu mu zhujian.
The purpose of this study is to explore the impact of entrepreneurial leadership on entrepreneurial performance in start-ups. Specifically, a moderated serial mediation model was developed to investigate the mediating role of tacit knowledge sharing and job embeddedness and the moderating effect of career growth opportunities. Data was collected from 376 start-up employees via an online survey platform. Using hierarchical multiple regression and Hayes' PROCESS Macro by SPSS 21.0, and structural equation modeling by AMOS 23.0, support was found for both (...) mediation and moderation effects. Results showed that entrepreneurial leadership significantly positively affects entrepreneurial performance by mediating with tacit knowledge sharing and job embeddedness. Moreover, career growth opportunities moderate the serial mediating effect of tacit knowledge sharing and job embeddedness between entrepreneurial leadership and entrepreneurial performance. This study provides theoretical guidance for entrepreneurial leadership to improve entrepreneurial performance. (shrink)
Producers have always been eager to know the reasons for the difference in the production of different shale gas wells. The Southern Sichuan Basin in China is one of the main production zones of Longmaxi shale gas, whereas the shale gas production is quite different in different shale gas wells. The Longmaxi Formation was deposited in a deepwater shelf that had poor circulation with the open ocean, and it is composed of a variety of facies that are dominated by fine-grained (...) particles with varied organic matter distribution, causing heterogeneity of the shale gas concentration. According to the different mother debris and sedimentary environment, we recognized three general sedimentary subfacies and seven lithofacies on the basis of mineralogy, sedimentary texture and structures, biota, and the logging response: There are graptolite-rich shale facies, siliceous shale facies, calcareous shale facies, and a small amount of argillaceous limestone facies in the deepwater shelf of the Weiyuan area and graptolite-rich shale facies and carbonaceous shale facies in the Changning area; there are argillaceous shale facies and argillaceous limestone facies in the semi-deepwater continental shelf of the Weiyuan area and silty shale facies in the Changning area; and argillaceous shale facies mainly developed in the shallow muddy continental shelf of the Weiyuan area, whereas silty shale facies mainly developed in the shallow shelf of the Changning area. Judging from the biostratigraphy of graptolite, the sedimentary environment was different in different stages. (shrink)
This paper deals with some points about the translator and contents of a Chinese Buddhist scripture, the Chengju guangming jing. It analyses the links between some historical figures and this scripture, scrutinizes passages of the text closely similar to other scriptures, and clears some doubts over the credibility of its translation. In doing so it is hoped that a better understanding of the authenticity of the text in general and a reliable ascription of translatorship of the scripture in particular can (...) be established.

The eastern part of Tazhong area in the Tarim Basin consists of three sets of vertical strike-slip faults oriented in north–northeast, east–northeast, and west–northwest directions that cut the strata from Cambrian to Carboniferous. The fault belts indicate significant horizon upwarp and downwarp deformations and variations in their stratigraphic thickness on seismic profiles. Through detailed interpretation of the 3D seismic data, we consider that these phenomena reflect the different stress properties and active stages of the faults. The horizon upwarp and downwarp (...) within the fault belts correlated respectively to the decrease and increase in stratigraphic thickness within the fault belts in comparison to the coeval counterpart of the bilateral fault blocks. For the same fault, different stratigraphic intervals express different types of horizon deformation and thickness changes. The horizon downwarp and the contemporaneous stratigraphic thickening inside the fault belts suggest the transtensional actions of the fault. The horizon upwarp and the contemporaneous thinning within the fault belts suggest transpressional actions of the fault. Based on this, we inferred the active periods of the three sets of strike-slip faults. The north–northeast-striking faults were formed in the late Ordovician Sangtamu Formation. This set of faults experienced four stages, i.e., sinistral transpression, sinistral transtension, static, and transtension. The east–northeast and west–northwest-striking faults initiated in the mid-Cambrian period as coupled transtension. Activity ceased in the west–northwest faults after the mid-Cambrian and in the east–northeast faults during the late Ordovician. The three sets of strike-slip faults all affect the formation of the hydrothermal dissolution reservoirs that are distributed in the Ordovician carbonate rocks. (shrink)
In an effort to fulfill the commands of Chairman Mao and Premier Zhou, our people are working strenuously to build our country into a powerful, modernized socialist state before the end of the century. Following the gradual progress of the four modernizations, the productive forces will rapidly grow, and the socialization level of production is bound to rise noticeably. How to understand the socialization of production, how to promptly readjust the relations of production and the superstructure in order to fit (...) in with the new situation in which the socialization level of production is continuously on the rise, and how to reform the management of industrial and agricultural enterprises as well as the administrative system of the national economy in order to quicken the speed of economic development pose a new problem calling for earnest study and exploration.
