Shale oil and gas have been discovered in the lacustrine Zhangjiatan Shale in the southern Ordos Basin, China. To study the distribution of extractable organic matter in the Zhangjiatan Shale, geochemical characterization of core samples of different lithologies, scanning electron microscope observations, low-pressure [Formula: see text] and [Formula: see text] adsorption, and helium pycnometry were conducted. The content and saturation of the EOM in the pores were quantitatively characterized. The results show that the distribution of the EOM in the shale (...) interval is heterogeneous. In general, the shale layers have a higher EOM content and saturation than siltstone layers. The total organic content and the original storage capacity control the EOM content in the shale layers. For the siltstone layers, the EOM content is mainly determined by the original storage capacity. On average, 75% of the EOM occurs in the mesopores, followed by 14% in the macropores, and 11% in the micropores. The EOM saturation in the pores decreases with the increase in pore diameter. The distribution of EOM in the shale pores is closely related to the pore type. Micropores and mesopores developed in the kerogens and pyrobitumens and the clay-mineral pores coated with organic matter are most favorable for EOM retention and charging. (shrink)
The natural fractures in mud or shale directly affect the quality and efficiency of shale gas reservoirs, and fracture identification and prediction play an important role in drilling shale gas wells and making plans for reservoir stimulation. We adopted ant tracking technology for 3D poststack reflective seismic waves to identify the size and distribution of high-angle structural fractures in the Zhangjiatan shale of the Yanchang Formation in the Ordos Basin, which is a typical continental shale. The parameters for ant tracking (...) fractures are extracted from the investigation on outcrop, cores, and image logs. The prestack seismic diffractive wave imaging technique for the super-resolution identification of mid- and small-scale breakpoints can be used as the constraint conditions for ant tracking. The identified result of high-angle fractures was validated by the image logging and drilling gas logging results. The geologic and logging data indicate that the Zhangjiatan shale is mainly characterized by high-angle fractures and a smaller number of low-angle fractures. The fractures mainly trend in the near east–west direction, followed by the near north–south direction, and a small amount of fractures in the north–northeast and northwest–west directions. The average density of structural fractures is relatively low, but the cemented rate is only 15.7%, and most structural fractures maintain an open state. The identified and predicted structural fractures are mainly distributed in the southeast of well LP180 and south of well LP179. The higher gas shows from actual well drilling in shale directly correspond to the density and intensity of high-angle fractures rather than the matrix gas abundance in shale, which indicates that the sweet spot of gas production in shale is clearly controlled by structural fractures.

Este artigo tem quatro objetivos. O primeiro deles é mostrar que dois debates contemporâneos de grande importância para a filosofia política aristotélica – a saber, o debate acerca do laço que liga ou deve ligar os cidadãos de uma comunidade política e o debate acerca da importância da participação política no que diz respeito ao alcance da felicidade – devem ser compreendidos em conjunto com o mo- vimento hermenêutico que chamamos hoje de biological turn. Como veremos, a maneira como respondemos (...) a essas duas questões influencia ainda uma terceira, a saber, a questão acerca da importância e da função da lei para a comunidade política tal como pensada por Aristóteles. O segundo objetivo é resumir os principais argumentos apresentados nos ditos debates apontando sua pertinência e as suas falhas. O terceiro objetivo é ressaltar um ponto de considerável importância para ambos os debates que não recebeu a devida atenção por parte dos comentadores. Sendo impossível alcançar uma resposta definitiva a respeito das duas questões no espaço que temos aqui, o último objetivo do presente artigo é indicar um possível caminho para futuras investigações.

The purpose of this paper is to investigate how supervisor’s mental state and behavior choice affect the relationship between employees’ strong growth need and their innovation performance. Using 210 sets of supervisor-subordinate dyads data from two-wave survey, this research reveals that GNS has a significant positive effect on innovation performance, and leader–member exchange mediates the effect of GNS on innovation performance. Supervisor perceived status threat moderates the relationship between GNS and LMX, such that this relationship gets weaker for supervisors with (...) higher perceived status threat. Furthermore, supervisor perceived status threat moderates the relationship between GNS and innovation performance, such that this relationship becomes weaker for supervisors with higher perceived status threat. The study concludes with theoretical and practical implications, as well as future research avenues. (shrink)
Familiarity and green image influencing travelers’ green hotel patronage have often been overlooked in previous research. The aim of this study was to examine the relationship of the two dimensions of familiarity and the two dimensions of image with the overall image, satisfaction, and loyalty. The theoretical research model used in this study was based on the stimulus–organism–response framework. The research design for this study employed a quantitative approach using a purposive sampling method involving 488 student responses. The tests of (...) the proposed hypotheses were conducted using SPSS and AMOS. The results of the study showed that experiential familiarity and informational familiarity positively influenced cognitive image and affective image, respectively, while cognitive image had a positive influence on the affective image. In addition, cognitive and affective images have a positive influence on the overall image, and the overall image is shown to have a positive impact on satisfaction and loyalty. Finally, satisfaction was found to have a positive influence on loyalty, while satisfaction plays a partial meditation role in the relationship between overall image and loyalty. (shrink)
This study adopted a positive psychology perspective to investigate positive emotion and foreign language enjoyment among Chinese as a second language learners in an emergency remote teaching context amid the COVID-19 pandemic. A set of 90 preparatory Chinese language students was assessed for their level of foreign language enjoyment using the Foreign Language Enjoyment Scale. Participles' scores on self-perceived language achievement and actual test scores were adopted as the measurement of their Chinese language proficiency. The results revealed that: CSL learners (...) experienced high level of FL enjoyment in an online learning context, no significant correlation was found between FLE and leaners' actual language achievement nor between FLE and their self-perceived achievement, female learners showed higher FLE than male learners and gender was found to have a significant effect on FLE-Private, participants' geological location, i.e., whether in China or at home countries, significantly influenced their FLE, participants' regional group was not a significant predictor of FLE, and teacher-related variables and learner self-perceptions of achievement were strong predictors of FLE among CSL learners. The findings highlight the importance of teacher's role in an online learning environment and suggest that FLE may not boost performance in the short term for language beginners but is still conducive in the long run. Implications for both teachers and learners, and suggestions for future researches are provided. (shrink)

Although the history of adopting the Western Corporate Social Responsibility (CSR) concept in China spans less than 20 years, the core principles of CSR are not new and can be legitimately interpreted within traditional Chinese culture. We find that the Western CSR concepts do not adapt well to the Chinese market, because they have rarely defined the primary reason for CSR well, and the etic approach to CSR concepts does not take the Chinese reality and culture into consideration. This article (...) resolves these problems and contributes a new definition of CSR, called here – the Harmony Approach to CSR. Simply, the Chinese harmony approach to CSR means 'respecting nature and loving people'. It is the first time CSR has been defined in relation to Confucian interpersonal harmony and Taoist harmony between man and nature. Conceptually, this definition will broaden our understanding and will fit the characteristics of the Chinese market better. The idea of incorporating cultural contexts into CSR concepts could also contribute to future CSR studies. In business practice, it will help corporations to adopt CSR on their own initiative. The proposed virtues of traditional Chinese wisdom, in particular, will guide corporations to a new way of improving their CSR performance. (shrink)
The Exclusion Argument has afflicted non-reductionists for decades. In this article, I attempt to show that emergentism—the view that mental entities can downwardly cause physical entities in a non-overdetermining way—is the most plausible approach to solving the exclusion problem. The emergentist approach is largely absent in contemporary philosophy of mind, because emergentism rejects the Causal Closure of Physics, a doctrine embraced by almost all physicalists. This article, however, challenges the consensus on causal closure and defends a physicalist version of emergentism. (...) On closer examination, I find that neither physical evidence nor physicalist considerations can satisfactorily support causal closure. Moreover, I argue that two competing approaches that accept causal closure, compatibilism and autonomism, involve ad hoc postulations of mental causation. Therefore, all things considered, emergentism is the best option available to non-reductive physicalists. (shrink)
Point-of-interest recommendations are a popular form of personalized service in which users share their POI location and related content with their contacts in location-based social networks. The similarity and relatedness between users of the same POI type are frequently used for trajectory retrieval, but most of the existing works rely on the explicit characteristics from all users’ check-in records without considering individual activities. We propose a POI recommendation method that attempts to optimally recommend POI types to serve multiple users. The (...) proposed method aims to predict destination POIs of a user and search for similar users of the same regions of interest, thus optimizing the user acceptance rate for each recommendation. The proposed method also employs the variable-order Markov model to determine the distribution of a user’s POIs based on his or her travel histories in LBSNs. To further enhance the user’s experience, we also apply linear discriminant analysis to cluster the topics related to “Travel” and connect to users with social links or similar interests. The probability of POIs based on users’ historical trip data and interests in the same topics can be calculated. The system then provides a list of the recommended destination POIs ranked by their probabilities. We demonstrate that our work outperforms collaborative-filtering-based and other methods using two real-world datasets from New York City. Experimental results show that the proposed method is better than other models in terms of both accuracy and recall. The proposed POI recommendation algorithms can be deployed in certain online transportation systems and can serve over 100,000 users. (shrink)
Objectives: This study aimed to provide a comprehensive understanding of all intervention for learning burnout by meta-analyzing their effects.Methods: Relevant studies that had been published up to September 18, 2020, were identified through a systematic search of the PubMed, Web of Science, the China National Knowledge Infrastructure, and Wan Fang databases. Eligible studies included randomized control trials of any learning burnout intervention conducted among students. The Jadad scale was used to evaluate the quality of the study. Random-effect meta-analyses, subgroup analyses, (...) meta-regression analysis, and sensitivity analysis were conducted. Funnel plots and Egger's tests were used to evaluate publication bias. Duval and Tweedie's non-parametric trim-and-fill method was used to adjust the effect of publication bias.Results: Of the 5,245 articles found, 39 met the inclusion criteria for the systematic review. There were 3,400 students, including 1,847 students in the intervention group and 1,553 in the control group. A meta-analysis of 44 studies showed that the interventions were effective. Subgroup analyses were conducted according to education, scales, intervention measures, and intervention time. The results showed that, compared with the control group, the learning burnout scores of undergraduates, secondary vocational students, and middle school students were significantly lower. Based on different scales, all interventions were also effective. The funnel plot was asymmetric and consistent with the results of Egger's test. The trim-and-fill method was used, and seven missing studies were merged to obtain a symmetric funnel plot.Conclusions: This meta-analysis indicated that learning burnout interventions are effective. The subgroup analyses showed that group counseling is the most widely used, exercise intervention is probably the most effective, and 8 weeks or more is the appropriate intervention time. An integrated intervention study based on the factors of learning burnout adds value. More studies are needed to supplement the results in the future. (shrink)
We argue that analogical reasoning, particularly Gentner's structure-mapping theory, provides an integrative theoretical framework through which we can better understand the development of symbol use. Analogical reasoning can contribute both to the understanding of others’ intentions and the establishment of correspondences between symbols and their referents, two crucial components of symbolic understanding. We review relevant research on the development of symbolic representations, intentionality, comparison, and similarity, and demonstrate how structure-mapping theory can shed light on several ostensibly disparate findings in the (...) literature. Focusing on visual symbols, we argue that analogy underlies and supports the understanding of both intention and correspondence, which may enter into a reciprocal bootstrapping process that leads children to gain the prodigious human capacity of symbol use.

Dust plasma is a new field of physics which has developed rapidly in recent decades. The study of dust plasma has received much attention due to its importance in the environment of space and the Earth. Dust acoustic waves are generated because of the inertia of dust mass while the restoring force is provided by the thermal pressure of electrons and ions. Since dust acoustic waves were first reported theoretically in unmagnetized dust plasma by Rao et al., they have become (...) a research hot spot. In this paper, the excitation of dust acoustic waves by a gravity field in a dust plasma is analyzed. According to the control equations of dust plasma motion and employing multiscale analysis and perturbation method, we have obtained a -dimensional ZK model. Because of the space property of dust plasma, -dimensional ZK equation is more suitable than KdV equation and -dimensional ZK equation to describe the real dust acoustic waves. Then, the -dimensional time-space fractional ZK equation describing the fractal process of nonlinear dust acoustic waves is given for the first time. To further explore how dust acoustic waves change energy as they travel, we discuss the conservation laws of the new model. Moreover, we study the exact solution of -dimensional TSF-ZK equation by using extended Kudryashov method. Finally, based on the exact solution, we further investigate the effect of the parameter k, the charge properties of dust particle Zd0, the fractional order values α, β, γ, and θ, the temperature Td, the gravity g, and the collision frequency β0 and β1 on the properties of dust acoustic waves by a gravity field in dust plasma.

A growing number of philosophers are bringing interventionism into the field of supervenient causation. Many argue that interventionist supervenient causation is exempted from the fixability condition. However, this approach looks ad hoc, inconsistent with the general interventionist requirement on fixation. Moreover, it leads to false judgments about the causal efficacy of supervenient/subvenient properties. This article aims to develop a novel interventionist account of supervenient causation that respects the fixability requirement. The treatment of intervention and fixation that I propose can accommodate (...) some theoretical constraints on causation and deliver correct causal verdicts in classic examples. It is also worth noting that this interventionist account offers a promising defense of mental causation without postulating mental-physical overdetermination. (shrink)
The Exclusion Argument, which aims to deny the causal efficacy of irreducible mental properties, is probably the most serious challenge to non-reductive physicalism. Many proposed solutions to the exclusion problem can only reject simplified exclusion arguments, but fail to block a sophisticated version I introduce. In this paper, I attempt to show that we can refute the sophisticated exclusion argument by appeal to a sophisticated understanding of causation, what I call the 'Dual-condition Conception of Causation'. Specifically, I argue that the (...) dual-condition account of causation gives strong support to the so-called 'Autonomy Solution', which contends that even if mental properties are unable to cause (fundamental) physical properties, they can still cause higher-level properties (such as mental, behavioral, and social properties)—if so, human agency would be preserved in the physical world.

A quite popular approach to solving the Causal Exclusion Problem is to adopt a counterfactual theory of causation. In this paper, I distinguish three versions of the Causal Exclusion Argument. I argue that the counterfactualist approach can block the first two exclusion arguments, because the Causal Inheritance Principle and the Upward Causation Principle upon which the two arguments are based respectively are problematic from the perspective of the counterfactual account of causation. However, I attempt to show that the counterfactualist approach (...) is unable to refute a sophisticated version (i.e. the third version) of the exclusion argument in that the Downward Causation Principle, a premise of the third exclusion argument, is actually implied by the counterfactual theory of causation. Therefore, even if other theories of causation might help the non-reductive physicalist to solve the exclusion problem, the counterfactual theory of causation cannot. (shrink)
Este texto tem dois objetivos principais: apresentar o conceito de “lei natural” e aquilo que seria a sua expressão como “lei escrita” e, depois, reinterpretar este conceito a partir de uma perspectiva nietzschiana. Para alcançar este duplo objetivo urge, pois, em primeiro lugar, traçar, nas suas grandes linhas, as vicissitudes que atravessou a teoria da “lei natural” ao longo da tradição #losó#ca até a sua culminância naquelas correntes do direito natural, típicas dos tempos modernos. Convém também assinalar que este conceito (...) encerra no seu bojo, como derivações, as noções de necessidade, de #nalidade e providência. Eis por que, para interpretá-lo e criticá-lo, são utilizadas algumas intui- ções e análises de Nietzsche que, ao longo de sua obra, não cessa de se referir, direta ou indiretamente, a estas questões e, também, àquela de acaso. Não se trata, portanto, de simplesmente apresentar uma crítica de Nietzsche aos conceitos de “lei natural” e “lei escrita”, mas, principalmente, de examiná-los à luz de seu pensamento. (shrink)

A causalidade diz respeito à ligação entre dois eventos em que um causa o outro. Essa ligação deve ser necessária e permanente, ou seja, o primeiro evento causa o segundo sempre e irrevogavelmente. Suspeitas quanto à validade do princípio de causalidade são recorrentes em filosofia, parecendo estar nas investigações de David Hume sua melhor crítica. Contudo a causalidade se põe como essencial e inevitável na formulação de inúmeras leis científicas. Por sua vez, essas leis, desde as críticas da epistemologia do (...) século XX, são tidas por contingentes ou revisáveis. Nossa questão é: como compatibilizar a contingencialidade das leis científicas com a necessidade da causalidade kantiana? Para tanto faremos o seguinte: 1) Analisaremos a vinculação entre tempo e a relação de causa e efeito para a compreensão de Kant da causalidade; 2) mostraremos como se dá a diferença e relação de dependência entre a causalidade kantiana e as leis causais físicas; 3) finalmente nos encontraremos com o sentido kantiano da necessidade e revisibilidade das leis físicas.

This study investigated the status quo of article retractions by Chinese researchers. The bibliometric information of 834 retractions from the Web of Science SCI-expanded database were downloaded and analysed. The results showed that the number of retractions increased in the past two decades, and misconduct such as plagiarism, fraud, and faked peer review explained approximately three quarters of the retractions. Meanwhile, a large proportion of the retractions seemed typical of deliberate fraud, which might be evidenced by retractions authored by repeat (...) offenders of data fraud and those due to faked peer review. In addition, a majority of Chinese fraudulent authors seemed to aim their articles which contained a possible misconduct at low-impact journals, regardless of the types of misconduct. The system of scientific evaluation, the “publish or perish” pressure Chinese researchers are facing, and the relatively low costs of scientific integrity may be responsible for the scientific integrity. We suggested more integrity education and severe sanctions for the policy-makers, as well as change in the peer review system and transparent retraction notices for journal administrators. (shrink)
This study examines Chinese undergraduates’ perceptions of plagiarism in English academic writing in relation to their disciplinary background, academic enculturation, and gender. Drawing on data collected from 270 students at two universities in China, it finds clear discipline-based differences in participants’ knowledge of plagiarism and perceptions about its causes; an enculturational effect on perceived acceptability of and condemnatory attitudes toward plagiarism, with senior students being less harsh than their junior counterparts; and complex interactions among disciplinary background, length of study, and (...) gender. Furthermore, it reveals conceptions of legitimate intertextuality differing from those prevalent in Anglo American academia and clearly punitive stances on perceived plagiarism. These results suggest the need to take an educative rather than punitive approach to source use in English academic writing. (shrink)
